I worked with support over two weeks or so. I think some of it was AI, but I did eventually get to chat online with a person in support. The final response was that SCORM is not native to Canvas so it will only function as an "add-on." The result of this is that I would always have to upload and set up every single SCORM video. There will never be a way to copy such videos to other courses.
On my own I tried putting the videos in modules, on pages in modules, and I tried copying every way under the sun, including copying the entire course. The copy or the new course would always generate a "Page Not Found" message when clicking on the SCORM video.
I may try experimenting with using a Moodle LMS, as SCORM is native to Moodle, or so I believe.
If you can ever make SCORM files copy, please do post about it. If I come up with a way to make this work on Moodle, I could post about it as well, but I seriously doubt that I would be able to link the grades; I would have to manage them separately.
Best regards,
Bill
