We've received about three different reports from instructors that students are unable to view their quiz grades because of the message "Your quiz grade is muted. Your quiz score is unavailable..." The instructor has not muted the quiz in the gradebook and they have tried muting and unmuting it just to see if that would correct the issue but that hasn't helped. I saw on another question that someone was having trouble with something similar for practice quizzes and it had something to do with last Saturday's update. Later they said the bug was fixed but it appears that it's still a problem at my institution. How shall I proceed?
