Zoom Whiteboard becomes View-Only after several days of creating

[TopKicker]

If I create a new whiteboard during a meeting, we can both use it without a problem for that meeting. The next day the whiteboard still shows normal status with no View-Only tag.

A week later, when we meet again, the whiteboard has a View-Only tag added to it automatically without me even logging into zoom or doing anything in between that time. This happens every week when I meet with my teacher.

It can not be removed, you can not choose Collaborating when opening the board because it thinks I am not the owner of my own board.

You can not touch (iPad) or click (PC) on the View-Only displayed at the top to change it in any way.

You must copy the board and create a new one, which will again become View-Only automatically after a week's time before the next meeting.

How in the world do you remove this tag or prevent it from ever being applied to your board in the first place and how do you allow yourself to choose Collaborating.

Also how do you mute the volume on the iPad so you don't hear yourself talking when using a tablet as a whiteboard during a meeting. The tablet is just for drawing on the whiteboard, it shouldn't be trying to host the entire meeting as the PC is doing this job.
