Also the UI sucks. It doesn't blend nicely with my system. It looks like a sore thumb Windows 3.0 app or quack-age MacOS app in the midst of a futuristic OS.
Yes! Like there's a required two clicks to leave a call, you can't trust if it will start video on or off, the menu bar hides by default! The UX is horrible.
The 2-click to leave is aweful. Sure, accidental leaving can be annoying. How about don't put the button near anything else that might need clicking so that it's much less likely to be accidentally clicked.
