Due to a recent Panopto LTI update, an unforeseen issue has occurred where pre-existing Panopto video quiz assignment scores may not automatically sync to the Canvas gradebook.
The current workaround involves simply re-editing the existing Panopto video quiz assignment and re-selecting the video.
Select Assignments in your Canvas course
Edit the Panopto video quiz assignment
Select More Options
Under Submission Type, click Find
Select Panopto Videos from the list
Choose Grade on quiz results and click Continue
Re-select the same video quiz and click Insert when done
