I used Teams through most of lockdown. The developers were all on macs, and used slack for chat, so the only feature of teams we used was for the daily stand-up video call. The desktop app ran very poorly on macs, and left everyone pretty much blaming it whenever their Mac acted up. I only used the website version myself, and it was fine, so I'm assuming there was just some hanky programming in an election wrapper that needed optimizing.
