Issue: When reopening a discussion for an individual student with an additional availability/due date, the individual student is unable to reply to the discussion because they are seeing a message saying that it is closed for comments. Canvas is not recognizing the new availability/due dates set for the individual student. 
Status: Canvas engineers are investigating the issue.
Workaround:

1. Click on the title of the Discussion.
2. Click on the three dots to the right of the discussion.
3. Select Edit.
   
4. Scroll to the bottom of settings. In the Assignment Settings section, make a note of the due and availability dates set for Everyone Else as you will be adding this back in steps 7-11. Remove the Everyone Else Assign to criteria by clicking on the trash can icon to the right.
   
    
5. Click Save.
6. Click Continue on the warning box.
7. Click on the Assign To button in the upper right.
   
    
8. Click on +Add.
9. Click on the assign to box and select Everyone Else.
10. Add back the original due and availability dates.
11. Click Save.
     

Issue: Graded discussion not appearing in Grades or Assignments tab or Assignment group showing up multiple times in the assignment group selection drop down list. This is due to deleted assignment groups still appearing in the Assignment group selection drop down list in the discussion settings. If the graded discussion does not appear in grades or the assignment tab, the Assignment Group it was assigned to no longer exists in the course.
Workaround: If your graded discussion is not appearing in the Assignments area, edit the discussion and select a different Assignment Group in the list. Note: You may see the same assignment group name listed multiple times in the list.

Issue: Removing the available from or until date does not clear it from the discussion and students may not be able to reply to discussions because it is closed.
Workaround: 

1. Click on the discussion and click on the Assign To button in the upper right. 
2. Enter an Available From and Until date set to the future. 
3. Click Save. 
4. Click on Assign To again.
5. Click Clear next to the availability dates.
6. Click Save.

Issue 1: Student are not seeing the "Attach" icon when responding to discussion posts. By default, students do not have permission to attach files in discussions. 
Fix: The "Attach files to discussions" setting will need to be enabled by following these instructions.

Issue 2: With the Attachment icon enabled, students are still unable to attach or embed files into discussions. This can be caused if your My Files section has exceeded the limit. 
Fix: Access your My Files and free up space by deleting any old files in the conversation attachments or in Files. You also have the option to download those files prior to deleting them.

On a Mac:

1. Open Safari and from the Safari menu, click on Preferences.
2. Click on Privacy
3. Uncheck "Prevent cross-site tracking"
4. Quit and reopen Safari

Issue: Students are given a "You Need Permission" error when trying to access Google Drive documents shared by their instructor. 
Description: We have two separated Google domains, Rebelmail (@unlv.nevada.edu) and UNLVMail (@unlv.edu). By sharing with "Anyone at UNLV with the link," it will only share within UNLVMail and it will not be available to Rebelmail users. 
Fix: Change sharing settings to "Anyone with the link."

Browser impacted: LockDown Browser 
Issue: For a course that contains an exam that requires LockDown Browser and a Webcam, when students click to begin an exam they encounter the following error: Unable to Continue - Exam title indicates a webcam must be used, but the course is unknown to our system. Solution(s): Ask your instructor to go to the "LockDown Browser Dashboard" for this course and check the setting for this exam. 
Fix: The error is often caused if the course is a copy of another course, and the instructor has not yet opened the LockDown Browser Dashboard in the new course. It can also be caused if the quiz you are trying to take has been migrated into your course from an older one. Once the instructor clicks on the LockDown Browser link from their course menu, the problem will typically be resolved.
