[iOS] Whiteboard Visibility Issue on iOS: Initial Drawings Not Visible to Other Participants Until Whiteboard is Reopened

[Rabeb-Ch]

What happened?

I’m encountering an issue with the whiteboard feature in Jitsi on iOS. When an iOS user is the first to draw on the whiteboard, other participants are unable to see any of these initial drawings. The only way for other participants to see new drawings from the iOS initiator is if the iOS user leaves the whiteboard and then reopens it to continue drawing. This workaround does not resolve visibility for the initial drawings.

Steps to Reproduce:

1. Start a Jitsi meeting on iOS.
2. Enable the whiteboard feature and begin drawing as the iOS initiator.
3. Observe that the other participants cannot see any of the initial drawings made by the iOS initiator.
4. As a workaround, the iOS user leaves the whiteboard, reopens it, and continues drawing.
5. Other participants can then see the new drawings, but the initial drawings remain invisible.

Expected Behavior:
All participants should be able to see the whiteboard content in real-time, including the initiator’s initial drawings.

Actual Behavior:
Other participants cannot see any of the initial drawings made by the iOS initiator. Only after the iOS user leaves and reopens the whiteboard do participants see new drawings, but the initial ones are never visible.
