If a student turns in a paper late, after I have finished grading that of other students and thus unmuted the assignment, I would like to be able to grade that paper without the student getting constant notices that I have created comments, or to see my grading while I do a first pass and then finalize a grade later. If I mute the assignment, then all the students in the class will get an email when I unmute it again. I'd like to avoid overloading their inboxes or advertising that a student has turned in a paper late.
Mute/Unmute is now Post Policies. You can find more information in the Canvas Release Notes (2019-07-13) .
