Can I re-sync the Realize grades for an assignment back to LMS Gradebook?

Currently you cannot re-sync the grades from Realize back to your LMS course. You will need to manually correct any grades that may need to be corrected.

Note: if you change the grading options after your students received their grades for an assignment, such as you change the max points, you will need to manually correct your students' grades in both Canvas and Schoology.
