Thank you for your continued feedback. The feature team is actively working on this highly requested feature. We are testing the first release that will have the ability for meeting hosts to create breakout rooms, assign the users to the rooms and call them back to the main room. Please see our roadmap for current status here: https://www.microsoft.com/microsoft-365/roadmap?filters=Microsoft%20Teams&searchterms=65332.
Unfortunately because of changing priorities, this feature was moved to the backlog. The team hopes to pick it up again in the near future.
