Breakout Rooms Closing Unexpectedly

Hi,

We are having an issue with breakout rooms that are closing unexpectedly.

When it occurs, it isn't happening for all breakout rooms-- just 1 room out of the many.

We send an announcement to the rooms that they have 1 minute left and as the time counts down, a room will be kicked out and returned to the main Zoom at the 40 second mark.

What could be happening here?
