Restart Your Computer, and Update Your Device
If updating your browser didn’t resolve the issue, restart your computer, and then log back into Canvas. This is also a good time to update your device:
Check Your Browser Configuration
Many media-playback issues are caused by browsers, including cookies and browser extensions.
- Switch to a computer running Windows or MacOS if you’re not already doing so.
- If you’re using Safari as your browser, please switch to either Google Chrome or Mozilla Firefox when working in Canvas.
- If you’re already using Google Chrome or Mozilla Firefox, try switching to the other browser.
If switching between browsers fixes the issue, then your previous browser is likely causing it, and will need to be reconfigured. Chrome should be configured to not “Block all cookies” or “Block third-party cookies.” Firefox will need to be configured to allow cookies as well. Finally, after changing either of those settings, clear your browser cookies.
