I was almost finished with the course(91% complete) but just as I was about to submit the final quiz, I was given the ‘Upgrade to Submit’ option. I understand that the deadline has passed, but it is not letting me repurchase the course. The ‘Upgrade to Submit’ button is not working.
If you go to the course intro page (then one you reach from the course catalog), does it have an “enroll now” button?
No, it doesn’t. It shows ‘Already enrolled’, ‘Go to Course’.
I think you’ll have to contact the Coursera Learner Help Center.
