I want to use polls for hybrid teaching setting, where part of the participants are logged into Zoom from remote locations and part is sitting in a room with the lecturer (without being logged into ZOOM).

When I start the poll the remote-participants can answer via ZOOM.

The others can answer using the QR-Code and smartphone to answer (they are not logged in with ZOOM).

Is this last group somehow counted towards my max. meeting-participants (since they are not logged in) or not?

Could I have a meeting maximum of 100, have 100 people answering in ZOOM and additionally 50 people sitting in the room with the meeting host, using their devices to answer via QR-Code?

Please can anyone tell me if there is a way to turn off/change the audio for desktop meeting reminders?

The notification is so so loud, I don't have any issues with any of the other sound settings for various apps. I want to keep the popups that appear on the desktop, just remove the sound notification, or change it to something softer at least.

When I enter a meeting Zoom automatically uses my Google account (with private email and picture, which I do not want to use) instead of using the one I have logged in with (my work email and picture, which I would like to use).
Any solution to this, please?

Can I lock the settings of existing Break Out Rooms that I have created?

Recently I had 30 minute Break Out sessions in progress. While setting up the next set of Break Out Rooms, I accidentally started editing the participants in the sessions that were underway. Fortunately only minor disruptions took place until a Co-Host notified me.

Is there a way to lock the sessions underway while defining the next set of rooms?
