Hi @rrudd,

I think H5P might be wrong about this being something with Canvas (as evidenced by other 3rd party tools doing this just fine).  I'm a Canvas admin for my institution, and one of the most frustrating parts of my job is troubleshooting issues like this, as typically the 3rd party will blame Canvas, Canvas will blame the 3rd party, and we're stuck in the middle.  What I generally do is submit tickets with the 3rd party and with Canvas, and reference those ticket numbers in both tickets.  Sometimes this helps with communication.  This may be something that you'll just have to keep pushing on though, unfortunately.

Hope this info helps, even though I know it's not a complete solution.
