We have upgraded to Q4 2016, which has overall a good experience. However students provide feedback on the assignment tool not showing any progress when submitting one or more files. There is no feedback from the browser after the submit button is pressed. It is not a problem for small files but with larger files students get confused.
It is a known issue (Behind the Blackboard! ), but I hope someone has an alternative solution.
I have been playing around with the CSS and the submit button, but no luck so far.
