My video not working for my students but working for me

منذ ٣ أعوام

In the last three classes I have taught today, my video wasn't working for my students. I could see my video and their video, but they reported my video being black. My audio was working just fine and I was still able to teach the class. My video works just fine on zoom and on Facetime, so I don't know what's happening. Has anyone else experienced this today? Any advice for how I can fix it?
