Hi all. Happily flying my new MA2 and up popped this message on-screen of my iPhone 6S. Flight was fine (20mins), no glitches and snapped a few stills. Didn’t have Airplane mode switched on (which I stupidly forgot to do!!) but everything else was as before. The phone was hot and down to 14% when I returned home (it has a new battery) and pretty certain I started off with a virtually full battery. Never happened before. Would value input.
