New Zoom Whiteboard - participants can't add to it
I love the look of the new Zoom Whiteboard, and I was so excited to try it with colleagues.
I created a whiteboard on my zoom account and then shared it by clicking on the bottom task bar in a meeting.
The participants could see my whiteboard and I could add to it, but they couldn't.
I've enabled the in-meeting whiteboard on my online zoom admin account:

I then tried to share directly to participants emails, but it said that I couldn't share as it was disabled by my administrator: this is someone from within my organisation.
Any ideas please?
