I'm aware that this is a known issue in Mastery Paths and advised to submit a feature request.
When a student completes a Mastery Paths enabled quiz in a module, the "next" button displays a processing message popup on hover and advises the student to refresh the page before clicking next.
This workflow assumes that the student sees the message before clicking on the Next button. If they click while processing is still running they are booted out of the module flow and into the list of module items, which is undesirable.
Here's a video demo I created of the problem: https://support.mivideo.it.umich.edu/media/t/1_nx70moih
Here's the Q&A post I made where I originally asked for help: https://community.canvaslms.com/message/115648-re-how-do-i-prevent-students-from-being-kicked-out-a-masterypaths-module-…
