I am a student user of Canvas and find it distracting (read - annoying) when a grade is entered into the Canvas gradebook and I cannot clear it or mark it as "read." There is an "unread" notification on the Grades sidebar and the blue dot will not disappear. How can I clear these? Opening the graded assignment does not work and there is no way to click the blue dot to "mark as read" as there is within the Discussion forum.
