I've written about this before, and submitted a bug report as well...but still having the problem. Whenever I make inline comments on my student's submissions, they disappear once I enter a grade! I'm NOT talking about comments made in the "Comments" box--it's the comments I make ON the assignment itself using the "T" tool. I've been using Canvas for years and have never had the issue before...and it's creating huge problems for my students who aren't getting my feedback. Any ideas?
