Known Issues

Below are a list of known issues with Canvas. Click on the item below to view more details regarding the issue and suggested fixes/workarounds:

General Issues

Browser Impacted: Chrome 
Issue: Users are experiencing issues accessing Canvas and/or accessing content files using the Google Chrome browser 
Suggested Workaround: Download Firefox from the Google Play Store 
 

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."

LockDown Browser

Browser impacted: Chromebook OS only - Chrome with LockDown Browser Extension Enabled
Issues: 

  • Limitations: Editing Spreadsheet tool and special accent characters not currently supported for the Chromebook LockDown Browser extension.
  • Known Issue: For exams that contain essay questions in between other question types and the quiz is set to display all questions at once, the essay question answer box is appearing behind the next question and students are unable to type in their answers. 

    Fix/Workaround: LockDown Browser version 0.3.00.473 was released on April 3, 2025. This version should fix the issue above. The LockDown Browser update should automatically download and install to a Chromebook as long as your Chromebook settings don't prohibit updates to extensions. If you don't see this version number for the extension, you may need to restart your Chromebook for the update to download and apply.

Tool/Browser impacted: New Quizzes & LockDown Browser 
Issue: When students attempt to view their results for a New Quizzes quiz that is no longer available, they are encountering a 403 forbidden error telling them they must use LockDown Browser to view the results. Error persists even in LockDown Browser. This is a known issue and Canvas engineers are working on a fix.

Workaround: Extend the available until date.

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.
