I am currently a student at a state university using Webex for online classes. I am having an issue in one class only, but not all of the other students are experiencing it. When the instructor switches his video to his camera, I only see it when I am in "grid view". When I try to switch to "active speaker video view" in order to see it full screen, I get no video and the error message that I have attached pops up in the top left corner of the Webex window. When the instructor shares his computer screen, I have no problems. I am using this on an iMac, but I do not think this is the problem.
I very sincerely doubt that what this message states is true of my computer. For many reasons, including the fact that this is the only class where this happens, I do not believe that this is the problem. Does anyone have any ideas?
