Automatically sending people to breakout rooms

Hello

I want to be able to manually select who is going into each room, but once I send people to those rooms, I want them to automatically be sent there, instead of being presented with a "Join Breakout Room" button.

I thought the "Automatically move all assigned participants into breakout rooms" would do this, but we ran a test session and it didn't work.

Is this not the right setting, or did that setting just not get applied for some reason? Do we need to restart the machine and try again?

Thanks
