I uploaded a series of videos today and can't figure out why they won't play in preview. I uploaded a series of videos yesterday and those videos work fine. The settings haven't changed and the only difference is the videos today are talking head while yesterday's were screen recorded. They were all produced the same way using the same software.
I'm not sure if it's a setting on my end or if Udemy is having problems of some sort. I cleared my cache, tested incognito browser, restarted my computer etc. Nothing works so far. All I get is a black screen and a broken player. A message pops up after a few moments asking if I want to allow flash, so I press allow, but that does nothing. Then I get this error:
