I flew my new Phantom 3 Pro today for the first time. I'm confused about the flight mode when I press the Video Record button. The P3P boots up, saves home point and I get a green Ready to Fly GPS Mode indicator at the top of the Pilot App, but as soon as I press the Video Record button it goes into P-Opti mode. Anybody have this problem? Both the P3P and Controller have firmware successfully updated to the latest version.
