Hi @makinglemonade when switching devices, are you using the same Zoom account on both? Or are you switching accounts while using different Zoom login credentials?

You will be able to'switch' between devices if you use the same account on Mobile, Tablet, and Desktop.

Desktop View (this is disabled because I joined the same meeting on both devices; if you are not already in the meeting on another device, it will be available to you)

Mobile iOS view. 

Hope this helps!
