I have a non-graded assignment in which I have selected the options "Worth 0 points" and Display grade is set to "Points" with the checkbox enabled "Do not count this assignment towards the final grade." I have been giving free-form comments to the students on the assignment, but they are unable to view them. They only see the comments they themselves have submitted. I tried unchecking "Do not count this assignment towards the final grade" and it still didn't work. Any advice?
