Here's a first for me. Was flying a P3Pro yesterday. Hovering at about 25 AGL feet taking pictures. Had only been flying for about 5 minutes on a fully charged battery. The Go App announced "You have reached the maximum flight altitude" and began to swiftly descend. Fortunately I was able to move forward and hand-catch it. Then did the CSC stick command to cut power to the motors, but that didn't work. Had to push the battery button to cut power. Firmware upgrade was done about 2 weeks ago on Phantom and RC. And I had reinstalled the DJI Go App at the same time. Had done 4 flights since then. Had done a compass calibration before this flight, Safe to Fly GPS Mode, Home Point established before takeoff. Anyone else hear of this before? I will not be flying until I can resolve this.
