Our teachers enter assignments/grades into Canvas. Then they sync to PowerSchool's gradebook, PowerTeacherPro (PTP). PowerSchool is our SIS. Comments do not transfer from Canvas to PTP with the sync, so teachers are going into PTP and adding comments for some students. The next time the teacher uses the sync for a different assignment, the previous comments are deleted. This is very frustrating. 

Is anyone else syncing grades from Canvas to PTP? If so, have you found a way to keep the comments that are entered into PTP without the next sync erasing them?
