I'm using 5.17.5 on my iPad Pro OS 17.2 (21C62)

I see on the release notes (https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0073923) that "Users have the option to switch back to the classic Whiteboard via their meeting settings. Under In Meeting (Basic) settings, users can click the Use Whiteboard by default if available toggle to seamlessly revert back to the classic Whiteboard in their next meeting."

I'm not seeing this anywhere. Suggestions? 

I have a Powerpoint that I present in meetings. I've created a whiteboard as an interactive part of the presentation. Can I insert the whiteboard into the Powerpoint and have it remain interactive and functional? As it is not, I have to stop sharing the Powerpoint, share the whiteboard, stop sharing the whiteboard and start sharing the Powerpoint--at which point it goes back to the beginning. It's really a clunky process while you're live. I see that there is an iframe code for the whiteboard but I can't see how to insert the code on a Powerpoint slide. Any suggestions?

I have set up a number of whiteboards (have purchased the whiteboard add on license) and want to share the whiteboards in separate break out rooms. I want the groups to edit the whiteboards in the breakout rooms and bring them back to the main group.

I have not been able to find out how I can share the whiteboards with the breakout groups, I am unable to share the link in the chat as the main chat is wiped when they go into break outs. If I send it as a broadcast message they can't click on the link.

Even if I make it one whiteboard to share across all groups I can't not share it to the breakout rooms like you can with a shared screen.

I have reviewed all similar questions in the community and have found no solution, I have done the training with no solution to this problem shown. Please advise.

Is it possible to add a "lock" feature, which locks properties of an item while keeping it movable?

I use whiteboards in teaching: students should arrange several objects into correct order. It is annoying to see the students constantly changing the size of objects or accidently adding arrows, while trying to move them...
