Camera Control settings not working

Hi everybody,

The Camera Control from the top settings menu isn't working.

I have the latest versions of firmware and software as following :

DJI Phantom 4 with :

iPad Air 2 with iOS 9.3.5
Map Pilot 2.1.5 build 08292016
Aircraft 01.02.0503
Remote Controller 1.6.0
App (DJI GO) 2.9.1

Map Pilot connects with aircraft : "Aircraft Detected : Phantom 4"

"RAW image" options purchased.

Show Image Footprint is OFF

PAS switch is set to "P"

DJI GO is surely closed.

It previously worked, most probably stopped after last Map Pilot update.   

Any idea ?
