I seem to have lost flight modes for my MM. It was working fine for a few weeks but seems to have disappeared since last firmware update. Now I just get an N/A on the top left of the screen where the flight mode should be. I uninstalled the app and reinstalled just now and lo and behold it reappeared. Unfortunately I turned everything off and back on again and it's gone again. Any ideas? Is it a know issue? Sorry if this has been asked before but couldn't find it when I searched.
