When I sign in, it shows me the main screen and then signs me out abruptly. I uninstalled the app and redownloaded and the same thing happened over and over.
I am having a similar problem, but Zoom is kicking me out 15-20 minutes into the meeting. I have also tried uninstalling and reinstalling the app and accepting the updates.
Double check and be sure you do not have 32 bit zoom installed. if it is use the zoom uninstall tool and install 64 bit. this ended up being our issue we had on pcs
