A new issue popped up that I've never seen before, and didn't start until very recently. Student video submissions load just fine, and I can click through the video, but they never start playing. I've reloaded, refreshed, restarted everything and nothing works.
The above screenshot will load, but the video never begins playback, I can pause/play and nothing. I can reload and nothing, I can click through the video and see that it did indeed record, but it never plays. Any idea what's going on?
