When I return a paper and my students click on View Feedback, instead of seeing the document with my comments on it, it merely opens the document they submitted, with none of my comments. This started 24 hours ago. I've reported the problem and tagged it as urgent, but I've had no answers. My students need to revise their essays ASAP based on my annotated feedback, but they won't be able to until this is fixed. Is anyone else having this problem?
