Hi @VictorChamness,

I'm at a university that uses Turnitin via the Plagiarism Detection Framework integration with Canvas.  As far as I know, resubmission to Turnitin is only available when the original attempt to get a Turnitin score failed.  You could be using a different integration type that functions differently, but for us at least, resubmission to Turnitin has never been available when everything works as intended and a score/report is generated.
