I see a lot of others asking this same question, so I know it is a common problem. How can we get Canvas to allow us to close the comments feature?  These are the main problems that I have:  

1.  I have strict no-late work policies (I drop the lowest grades instead).  Students are under the false impression that they can submit late work in the comments section.  They should not be able to work around the end date for my assignments.  

2.  Students send too many frivolous comments like, "thank you,"  "alright," and "okay."  They expect that I will see all of these comments but they only waste valuable time that I do not have for such meaningless comments.  

Please, please allow us to turn this off.  Faculty have clearly been trying to do so for years on this forum.
