In my Canvas quizzes, Quiz Statistics only shows responses for a few students. My campus IT specialists contacted Canvas about it, and the reply was that if anything in a quiz is changed, then Quiz Statistics only shows responses from before the quiz was changed. However, I did not change the quizzes after deploying. The only thing that was "changed" was that a couple of students receive extra time on quizzes. However, this should not affect the Quiz Statistics. Has anyone else run into this problem?
