Unfortunately I've run into the same problem twice. In one case playing with the grading system fixed the problem. In the other, however, we're still not getting the feedback. Also, the instructor uploaded a file for the students as part of the feedback and the students report that while they could see the files at first, they've disappeared. It's not clear if they could ever see the feedback comments. We're running 2.2. I've verified the problem but can't replicate it in by testing course.
