I've got confirmed reports from 4 courses so far that had quizzes deployed over the weekend. They report that they can see Grades for students in the gradebook, but when they go into the quiz details via Speedgrader, there are no details. Also, when they go to Moderate this Quiz, there are no attempts used for these students, it looks like they haven't taken the quiz.
In one of my courses, the teacher changed the quiz dates to give the students another attempt, and this attempt went through without a problem.
Has anyone else heard of this from this weekend?
PS, I've put in a ticket
