Grade not reporting in CANVAS

Since the Canvas SCORM update and patch in October, I've had success with the completion tracking accurately reporting to Grades. My modules include quiz questions, but correct answers are not required for completion. I use the Course Complete trigger on the final slide and publish to SCORM 1.2, reporting as passed/incomplete (which results in full credit or 0) and tracking using the course trigger.  

Most of my modules began working again after the patch, but one did need to be re-imported to track correctly. I use the same method to upload to Canvas as Cynthia mentioned above.

Maybe you could track completion with the Course Complete trigger and place this trigger on a slide only accessible once your 70% or higher is achieved on the quiz? With Canvas, I've found there's no guarantee it'll work forever, but it seems like others as well have had better luck tracking this way.
