Ever since we updated to version 3, students are now unable to upload their assignments. On the upload screen, this is what we see: http://d.pr/i/13utd. No option at all...I've checked everything I know to check, but I see nothing that changed. I'm attaching a screenshot of the assignment settings & overall activity settings.
