I'm trying to rewatch some lecture videos from a few weeks ago, and the first one was fine however the rest of them played as audio only, without the video of the lecture slides. I tried reloading the page and none of them worked, including the first lecture that originally did. I've already contacted my professor and everything is normal from her side. I have tried 3 different browsers, clearing my cache, and restarting my brower and laptop and nothing is working.
I have a test coming up soon on this topic and really want to review the lectures properly - how can I fix this??
