I have two questions to ask this wise group. 1. I am getting a new to me P4P and just sold my P3P adn P3S. How do I change the name, so that when I fly or the new owner flys my old birds the DJI app will list them with their new names, registration numbers and not the old ones? 2. In the DJI Go 4 app on my Ipad, the flight data shows in meters but on my Android phone all distances show in feet, How can I get them both in feet? I can't find a settings tab.
