Students get a message saying they can’t submit because they stopped their assignments early. - If students manually stop their recordings instead of letting the system record for the entire duration of the exercise, it will not let them submit because the recording is not the correct duration. If they are letting the recording stop on it's own (not manually clicking the stop button) and are still experiencing this problem, can you have a student that is having the problem make a short video demonstrating the problem? And then can you share that video with us at email@example.com?
Assignments that were already graded show now as not submitted. - Can you email us at firstname.lastname@example.org and let us know which assignment submissions (class/assignment/student) you are referring to?
