Teams is trash, don't lie like that. It's the single most frustrating piece of software i interact with at work.

Im not lying, I dont have any problems with them

Calendar and meetings are decent, chat is viable and I dont need more

Whats causing problems for you?

Frequently fails to connect, doesn't honor system audio device settings and frequency forgets its own, frequently fails to mark messages as read, sometimes even after hitting "Mark all as read," sometimes fails to send notifications on new chats, especially on my phone.

It's the least reliable chat program I've ever used.
