In my Week 2 graded quiz I can’t open it.
I had missed the deadline and now when I go back it just keeps on loading and doesn’t open
If it lets you try to open the quiz, then I doubt it’s a problem with overall access to the course or reset deadlines or the like. Just sounds like a “bad weather in the cloud” kind of issue. Can you open other quizzes or assignments from that course? Or have you tried the old “logout and login again” trick? Maybe that would get you a fresh instance on a different server VM.
