Looking for help on this topic which I've already brought to Canvas now three times and have had no resolution.
I have unit quizzes set up in my course that are designed to have students take, see answers, then retake, so they are able to test their knowledge and strengthen it with each resubmission. To do this, I have the quiz set up for unlimited attempts and set to show answers immediately. The quiz is open for a duration of a few days, then locks; I only grade after the quiz locks since the students are, in theory, studying and retaking before the lock date & time.
The first three quizzes worked without a hitch; students took and retook the quizzes with access to answers I had provided. This helped them review our unit, with an eye to how they might do on an upcoming midterm or final exam.
With the fourth quiz, even though I have identical settings, something had changed without my knowledge, and students could only take the quiz once before seeing a "quiz is muted" note, saying it was pending final grading from me. Two chats with Canvas help led to no resolution - I was told "this is how quizzes work," despite having demonstrable proof that the first three quizzes had not functioned this way. Unit four thus was a loss - without access to the answers, students could not self-evaluate, and thus didn't take the extra time to study and strengthen their knowledge.
Unit 5 is now live and is doing the exact same thing as unit 4. Another chat with Canvas help told me that it was because I had an "until date" in the assignment - that is, that the quiz would lock at a certain time - but removing this would solve the problem. It has not solved the problem.
I am now facing losing the methods I use to reach learning goals in a second unit, and this is significantly damaging my course at this stage. Since Canvas help seems to have no idea what is going on, I am reaching out to you all. What is going on, and what can I do to fix this?
Please, I am going out of my mind trying to get this sorted.
In the images; the first is our unit 1 quiz settings (the quiz that worked just fine), the second is the current unit settings (the quiz that is not working), and the third is a student's screenshot of the muted message that they did not receive for the first three quizzes but have for the last two.
