Breakout rooms wouldn't close; couldn't see all breakout rooms

Hi,

Problem 1:

I was the Zoom host for a meeting with close to 250 participants. I was on a MacBook Air. I wanted to use all 50 breakout rooms (not knowing it would only work for 200 participants), so I created 50 breakout rooms for Zoom to automatically assign the participants. I then wanted to see who was in which breakout room because I needed to move certain participants around, but I could only see breakout Rooms 1 - 22. Is there a way to be able to see all 50 rooms and move or exchange participants?

Problem 2:

When I clicked on "Close all rooms," not all of the rooms closed. And those that did closed very slowly. The button  to close the breakout rooms appeared several times, and I clicked it each time. But at least one participant was left in a room that wouldn't close (and she said she didn't have the button to click to leave the room). Was there something I could have done to close the rooms more quickly or more efficiently?

Thanks for your help.
