I am a long time pilot, used to the P3P. Bought a P4P V2.0 today and downloaded the DJI Go 4 app. Everything works in full auto, but when I click on the symbol for manual settings, it doesn't do anything. What is set wrong to get me there? I've tried everything I can think of, researched all over the interweb, even texted a friend in marketing at DJI. It isn't working, and I'd like to use it on a shoot Monday. All I need is manual control of shutter speed/aperture/ISO, but I can't get there. I can use my P3P, but it doesn't have all those controls OR the higher quality sensor. Can anyone shed some light on this?
