Hello @rgibson1
Thank you for contacting the Canvas Community. We're sorry to hear you've been experiencing issues with clearing the blue dot from the student's notification views. @Ron_Bowman posted some good other threads for options of clearing it as well. We always recommend them clearing their cache, trying another browser, seeing if they can duplicate it in the app, another wifi, etc. If none of those things have fixed it, you could contact Canvas Support. They do have a way to clear the user's cache on their end that (very rarely) is the cause of an issue like this and can help.
Because of the complexity of the issue, and the concerns for privacy, it would be best if you contacted Canvas Support directly to pinpoint the source of the issue and provide a resolution:
