Bypassing Waiting Room

[martalaura]

I use my private room to teach students for a large school district.

Students go to the waiting room when they first join my Zoom.

If a student should "fall" or disconnect from Zoom, they are able to return to my Zoom meeting by passing the waiting room (upon return).

This did not happen before. It appears to be an updated protocol.  
This is NOT a good situation for me as a teacher.  I need to have students always go through the waiting room process. How can I fix this?

I need:

Students/Zoom participants must go to the waiting room each and every time they want to join my Zoom meeting. If they leave my Zoom meeting and attempt to join it again, they must go to the waiting room again.
