Inbox
Sporadic appearance of emails without recipient list, cannot reply
- System: Canvas
- Problem: In Canvas inbox, users report that they occasionally see messages that have no list of recipients at the top. Those messages cannot be replied to. An error message is generated.
- Workaround:Do not reply to the message, but start a fresh message to the sender.
- Status: Under investigation by Canvas Engineers.

People with a large number of enrollments cannot send mail to groups
- System: Canvas
- Problem: If users are enrolled in ~50 or more courses, they will see a severe lag in the time it takes to populate the list of groups when trying to send an email. If the person is enrolled in even more courses (>100), the page will time-out before the list loads, preventing the user from sending the mail message.
- Workaround:If possible, reduce enrollments. If not possible to reduce enrollments, you may communicate with a group by going into the group home page and using announcements.
- Status: Under investigation by Canvas Engineers.

People with a large number of enrollments cannot use the More Courses option
- System: Canvas
- Problem: If users are enrolled in a large number of courses, they will see a severe lag in the time it takes to be able to use the "More courses" option when trying to send an email. It can take up to 5 minutes for all of the enrollments to load.
- Workaround:If possible, reduce enrollments. You can also wait for the enrollments to load, or use the courses drop down in the left hand corner to specify the course before you attempt to send a message.

To-Do List Displays Items To Be Graded That Are Fully Graded

Assignments
Group Assignments Broken by Deleting Group Set
- System: Canvas
- Problem: Instructor created a Group Set and an Assignment that was assigned to that group set. Later, the group set was deleted and recreated with the same name. The Assignment still appeared to be correct because the Group Set was named the same thing, but when students submitted, the Assignment treated every student as his/her own group. There should have been an alert when deleting the original Group Set that there was an Assignment attached and that the new Group Set would have to be re-attached.
- Workaround: Make sure that Group Sets assigned to an Assignment or Discussion are not deleted, or if they are, that the Discussion or Assignment gets re-attached to the new Group Set.
- Status: Under investigation by Canvas Engineers.

Differentiated Assignments
"Assign To" Field Not Populating Students Alphabetically
- System: Canvas
- Problem: Differentiated Assignments are displaying the first five students differently depending on the browser used. Within Chrome and Safari they are NOT listed in alphabetical order, within FF they are listing the first five in order.
- Workaround: None.
- Status: Under investigation by Canvas Engineers.
--Jen 11:43, 09 June 2015 (EDT) 1569569;00422360
"Assign To" Field Shows "Loading" instead of Student Name
- System: Canvas
- Problem: This happens based on the number of enrollments in the course and where they are listed in the list of enrollments. In testing, it would fail after 200th enrollment. So, any user you try to assign an assignment to after the 200th will show up as 'Loading...' as it seems Canvas times out after loading 200 enrollments. This does seem to only be a UI bug though as it does correctly assign them to the users and speedgrader shows correctly.
- Workaround: None.
- Status: Scheduled to be fixed in the March 12 update.

Speedgrader
- Tool: Crocodoc
- Problem: When an instructor uses Crocodoc annotations for a supported assignment submission type (primarily Word documents and PDFs), the Firefox browser frequently removes the last annotated comment when updating the score field in SpeedGrader. This behavior is a Crocodoc-specific limitation within Firefox that cannot be resolved by Crocodoc at this time. To warn about the effects of Firefox and Crocodoc annotations, Canvas displays a warning banner that says “Warning: Crocodoc has limitations when used in Firefox. Comments will not always be saved.” To avoid losing any annotations, instructors may choose to use another browser when providing Crocodoc annotated feedback, or try clicking the screen before navigating to another student.
- Workaround: Use another browser when providing Crocodoc annotated feedback, or try clicking the screen before navigating to another student.
- Status: Under investigation by Canvas engineers.

Box and Crocodoc are working together
- System: Canvas
- Problem: Students may encounter an informational text when submitting a document that reads similar to "Box and Crocodoc are working together...sorry for any inconvenience." Your submission will be viewable in the Box viewer instead of Crocodoc, however, this appears to be transparent for users.
- Workaround: The Box viewer is a fail-over reader for when documents are not able to be viewed within Crocodoc behind the scenes within Canvas. Canvas support has suggested that the documents may eventually display in Crocodoc.
- Status: Informational Only.

Differentiated assignment due dates
- System: Canvas
- Problem: When using differentiated assignments, the due date shows as "Due Multiple Due Dates" instead of the due date for the specific student.
- Workaround: Due dates can be viewed on the Assignment page before entering Speedgrader.
- Status: Under investigation by the Canvas Engineers

Speedgrader Times out
- System: Canvas
- Problem: In courses of more than 500 students, Speedgrader times out and client gets the error message “Oops that last request didn't work out.”
- Workaround: Go to Gradebook, filter by section (if there is more than one section associated with the course), then choose Speedgrader from the Gradebook. This should cut down on the number of students pulled into Speedgrader at once which should allow Speedgrader to load properly.

Some students can't see annotations in Croc-o-doc when the assignment is given to groups
- System: Canvas

Turnitin
- System: Canvas
- Problem: When a Turnitin report shows an exact match to another student paper in the Turnitin database, the instructor is instructed to click a link to request permission to view the original paper. This link does nothing at this point, and there is no way to see the original paper.
- Workaround: None
- Status: Under investigation by Canvas Engineers. Canvas Engineers report back this this issue cannot be resolved.

Settings
Imported "Ends" Date affects Course Behavior
- System: Canvas
- Problem: When importing content from one course to another, the "Starts" date and the "Ends" date in the previous semester (found under "Settings) can carry over into the current semester. If left in place, an "Ends" date that is in the past is negatively impacting course behavior. Examples include quizzes wiping out student submissions, and being unable to send emails to the course participants.
- Workaround: Remove the "Ends" date or update it to a date in the future.
- Status: Under investigation by Canvas Engineers. UPDATE - It has been shown that this is isolated to courses that had more than one import from a previous semester.

Conferences
Conferences with lengthy descriptions broken in Chrome browser
- System: Canvas
- Problem: If a conference is created with a lengthy description, the "start" button disappears preventing anyone from joining the conference The edit option is also gone so that the instructor cannot remove the description.
- Workaround: Keep the descriptions short (a few words) or don't use one at all. If you already have the problem, use FF browser to edit the description.
- Status: Under investigation by Canvas Engineers.

Preview Of Large PDF and PPSX Not Displaying
- System: Canvas
- Problem: Large PDF and PPSX files are not displaying in the preview tool. Users may encounter the error message "document could not be converted, please download it instead."
- Workaround: Download the files to view them. Or compress (zip) the PDF file, then transfer it to the Canvas site and have it auto-expand. The file will open properly.

Settings
Notifications
Notifications Not Being Sent to E-mail
- System: Canvas
- Problem: Users Not Receiving Timely Notifications After Notifications Settings Modification
- Workaround: We have recently received information that it may take as much as one week (even days) for a change in Notifications Frequency to take place. Thus, if today you were to change your Notifications Frequency from Weekly to ASAP, the change would not take effect until sometime early next week. We are investigating this issue and will provide additional detail as we get more information.
- Status: Informational Only

Notifications Not Being Received via E-mail
- System: Canvas
- Problem: Users are not receiving e-mail notifications
- Workaround: Ensure that your e-mail address is verified. To do this, click on 'Settings' in upper-right. Within the "Email Addresses" section, ensure that your @ufl email address is blue. If your @ufl email address is grey and italicized, this means it is not verified. To verify, click the address and follow the prompts to verify it. Until this is done, you will not receive any e-mailed notifications.

- System: Canvas
- Problem: Within an e-mailed notification, when a user clicks on the "View this message in Conversations" link, the user is taken into Conversations but no conversation is selected. The links for going to the specific message in the inbox currently do not function as intended.
- Workaround: View conversations from within the Inbox.

Grades
Gradebook displays incorrectly for courses with differentiated assignments after exporting grades with "mark ungraded as zero" chosen
- System: Canvas
- Problem: If a course has differentiated assignments so that some students aren't required to complete some assignments, AND "mark ungraded as zero" is chose, AND the grades are exported, the gradebook then displays incorrectly to the instructor. After the export, the gradebook is counting those differentiated assignments that should not count against the student as zero, dropping the students' grades. NOTE: Students view of their grades is not affected.
- Workaround: Clear cache and cookies in your browser to reset the gradebook to it's correct view
- Status: Under investigation by Canvas Engineers.

- System: Canvas
- Problem: When using "Message Students Who..." through Grades in a large enrollment course, an error occurs and it appears that the message was not sent; however, the message is sent to everyone in the course not just those who "have not submitted." etc.

Master Percentage Not Work as Intended
- System: Canvas
- Problem: The feature should require that a student achieves at least XX% of the questions within the (question) bank correct in order to achieve mastery, however, it currently only depends on whether they mastered the questions individually.
- Workaround: None at this time
- Status: Under investigations by Canvas Engineers.

Import Outcomes
'Edit Outcomes' Button Present On Imported Outcomes
- System: Canvas
- Problem: When importing an outcome into a course from the account level, the edit button appears and admins can make changes to an account level outcome inside the course.

Page Error Upon Attempting To View Account-Level Outcome's Aligned Item
- System: Canvas
- Problem: If you have an account-level rubric that has an account-level outcome as a criterion, attempting to view the outcome's aligned item (which should be the rubric) will give you a page error.

People
Quizzes
Auto-Submitted Quiz When Student Is Not Viewing Page Not Populating Score In Grades
- System: Canvas
- Problem: When quizzes that are automatically submitted while the student is not viewing the page, the submission isn't fully created/generated in the SpeedGrader or Gradebook. Grades will reflect a score of "0". The actual grade will not appear until either the student goes back to view their submission, or until it's viewed by the Teacher in the "Moderate Quiz" page.
- Workaround: Students should ensure to click "Submit" for their quizzes, or go back to view their quiz soon after it is auto-submitted. If the Teacher has any indication that a student may have taken the Quiz but it is not showing in the Gradebook, they should go to the Quiz, click on "Moderate This Quiz" on the right, then click the student's name to view the submission.

Quiz Submission
- System: Canvas
- Problem: We have noticed an issue with quizzes which are automatically submitted while the student is not viewing the page. When this occurs, the submission isn't fully created/generated in the SpeedGrader or Gradebook. It does not appear until the student goes back to view their submission, or until it's viewed by the Teacher in the "Moderate Quiz" page.
- Workaround: Quizzes will appear again once you view them from the "Moderate Quiz" page
- Status: Under investigation by Canvas Engineers.

Special Characters in Fill in the Blank Questions
- System: Canvas
- Problem: In Fill in the Blank questions, if there are any special characters (%$', etc) AND the answer is more than one word (Newton's Law), the student's answer will be marked incorrect, even if it matches exactly the correct answer given by the instructor.
- Workaround: If your answer requires special characters, use the "Multiple Blank" Fill in the Blank type questions. So the example of Newton's Law would display as two separate blanks "Newton's" and "Law" instead of one blank with "Newton's Law."

Canvas iPhone App: Create an Announcement
- System: Canvas
- Problem: Users are no longer able to create new announcements from within the app. The "horn" is missing from the upper-right corner. Announcements can be replied to (the arrow is in the upper-right corner) but a fresh announcement has to be created from the web browser. Users cannot create a new announcement on the iPhone and iPod.
- Workaround: Use desktop/laptop computer until this issue is resolved.
- Status: Under investigation by Canvas engineers.
