Microsoft Teams preview, Video playback is broken

This becomes even more critical now that Microsoft is starting the **bleep** practice of forcing me to use the new teams without even me wanting to. It just randomly decides to change to the new one without any user input. I switch back to the old one and it gives me a pop up asking "to change now or change later?", like f* off! I don't want to change, I can't participate in meetings with the new one because I can't see any one, it doesn't f*g work!
It's like Microsoft telling, "nope you can't have something that works, f* you! Go find some other platform if you want to have your meetings", thanks!
Fix your **bleep**! I paid money for it!
