Zoom Room whiteboard only shown on one display.

[neve]

I have a large Zoom Room with three displays.
Display 1 is a touch screen at the instructor's podium.
Display 2 is a projector for content.
Display 3 is for seeing the gallery or active speaker.

It works great for almost everything.

When I start a whiteboard, it is only shown on the podium display and to participants. I can't figure out how to get it to show on Display 2. This means that no one in the room can see the whiteboard which makes it useless. There is no Content Only option under View.

How do I get this to work?
