Excessive CPU load
Teams application is obviously having some kind of an issue, because when it's not in use and minimized to tray, the app loads CPU with 30% or even more. I just completely uninstalled it and will only plan to use it through browser. If it's not mandatory by my company, I wouldn't use it at all.
MS Teams often uses 150% cpu on the leptop. (intel core i7 8th gen) The fan is leading to bad voice qulity. This happens with no other communication application (hangouts, slack...).
If my boss would not require me to use it, I would not have it.
I agree, CPU usage is an issue - especially on laptops and notebooks which have to run on battery.
