Hi @vellis, I don't believe there are limitations to how many users can use the whiteboard. As long as the host has given annotation permissions to all participants everyone should be able to use the whiteboard, as far as I know. 😀
Hi! Zoom Team, Can we have more than one participants annotating on the whiteboard at the same time , with each participant cannot see what others are annotating , and the individual participant annotations are visible to host in grid view.
