I had issues for weeks (form the point we found there was even an issue) with some users not being able to create meetings with breakout rooms. Strangely, I also noticed their UI was different. Speaking with Microsoft support, after being elevated to engineers for a while, we found out the clients were being put into VDI mode which is used in virtualised environments and has features cut like breakout rooms (and a different UI). No solution was offered except delete %appdata%\Microsoft\Teams and HKLM:\\Software\Microsoft\Teams on each client when this comes up. We still have no idea how this is happening, we have Citrix Workspace installed for other purposes, but if it was that I'd expect it to affect all clients.

This has been my only real complaint in the ~8 months using the client
