Tomorrow my students take their final exam. Today, every single quiz (which is ungraded), told the students that
"Your quiz has been muted
Your quiz score is unavailable because your instructor has not finished grading it. When your instructor finishes grading this quiz, your score will be available on this page."
Needless to say, everyone is freaking out. Our campus Canvas support said that they will try contacting Canvas about it. The students quizzes are all ungraded and marked to show they their score and their answer once they've taken it.
