Our school uses Powerschool SIS. Recently, grades for some students aren't syncing over to Powerschool, but Canvas is saying the sync was successful. My grading categories match, the Sync to Powerschool box is checked, and due dates are entered and accurate. In a given assignment, some of the student's grades are syncing over and some are not. I'm assuming there must be some difference in how the students exist in the Canvas class, but I can't find it. Full assignments will all grades have successfully syncing in the past, the issue has just started occurring in the last few days.
