Got this message yesterday. Never had it before in 98 flights.. got a low temp battery warning before I took off, then about 8 mins into flight got the propulsion warning. It was very windy and cold, just brought it down slowly and the rest of the flight seemed fine. Still on 1.6 firmware.
just checked my go app (ios) and i cant find the pen thing that used to allow me to draw a flight path on my map, the rubber is still there in the bottom right but no pen icon. has it been removed ?.... i wanted to plan a flight route while at home.
