Currently, the learner has to refresh the page to continue after a mastery paths quiz. 

This seems more like a bug than a limitation. And, it's really difficult for low-level learners to be instructed to do that. 

Canvas support have at times said that this is 'intentional behaviour', yet sometimes it works and sometimes it does not. This is not a consistent experience and learners should not have to be instructed to 'somtimes' click refresh or even click refresh at all. 

This needs fixing as it's a great tool that cannot be used for e-learning in its current state.
