I've been trying to integrate the media recording tool into assignments with my students, but have found a flaw that is significant enough that I will stop using the feature. There is no feedback from Canvas once you've clicked 'Save' as to the status of the upload. No matter how many times I tell my students that they need to wait patiently, that Canvas will eventually upload the video, my students think that the screen or task has gotten frozen.
There needs to be a 'percent completed' status bar that shows up once a student hits Save after recording a video assignment. That will save me (and the Technical Support team) hours of dealing with student problems and complaints.
