Breakout room issues to assign user to a room

I got this back från MS support, seems a signed in Teams free users can't be assigned. :( 


"Breakout Rooms do not support users with Teams Free accounts due to product limitations"

"Currently, the only workaround is to use the browser in an incognito or private tab, or without signing into the browser, which will allow the user to join the Breakout Rooms."

We also still see issues with this. I've asked ms again what's going on. 

Problem still exists. We have big problems in collaboration with external guests. Users cannot be assigned in ~80% to break out rooms. All users have new Microsoft Teams (v2) and do not use MS Teams Classic anymore.

Microsoft support does not give any workaround or solution.

Hello Markus,

There's quite a lot of people facing frustration by the breakout room issue. I have made a thread myself, and there are others posted too. 

I was wondering if you have an update on the issue, and how you confirmed this was a code defect?
