We’re constantly working to improve your Plagiarism Framework experience and are happy to report that updated similarity scores will now show in Canvas on the assignment due date. 

In order to check for collusion or identify any updated matches, Turnitin automatically reruns the similarity score on the due date for an assignment. In the past, if there was a change to the score it was only reflected within Turnitin and not passed to Canvas. We've fixed this bug, and users will no longer experience this issue.
