Replying to an old post, but for those looking around...
You only get the multi-view options when the settings -> camera -display - advanced is set to fisheye not expansion.


also, you have to leave the fish eye options box open to be able to grab and move the views around.
the views reset every time you switch cameras/ open/ close the live view.

Don't see the fisheye options in the app.. Does anyone know how to activate in the app?? The above settings are for the desktop client.
