Teams implementation of copilot was done poorly. I'll use it sometimes by clicking copilot in the upper right corner. Its 50/50 after I use copilot in teams that a window will cover up the left side where all my chats are and it won't go away. I have to actually right click and quit teams to get the chats with people back up.

Clearly there was minimal testing by Microsoft before they rolled out copilot in teams.
