Then why did it work before?

I'd been using YouTube's new layout just fine on Edge Chromium for at least a week before getting the "not supported" message.

I haven't seen that yet, but Meet just started working for me. Previously it didn't.

Very happy with my Edge switch so far! And I did it before the ad blocking really reared its ugly head too.

Google needs to faceplant hard on this one.
