My M3E was unable to fly even with doing the mission creation on the RC DD app. It failed to initialize the camera every time. I confirmed I had Pilot 2 closed but it was still a no go. For reference my RTK module was on the aircraft as we had successfully completed 3 RTK (Pilot 2) missions before trying the DD app at the end of a day.
I will say flying in Pilot 2 with RTK and processing on DD gets great results so far. Anxious to get the DD app solid on the M3E.
