I'm experimenting with the button customizations with DJI Go 4 and Litchi, but these questions are mainly for DJI Go usage.
Does anyone know why there aren't C1 and C2 long press button customization options?
Also, have any of you tested out all of the button options you can, meaning do you know if they all do indeed work?
(I ask because I don't think at least one of them - metering/focusing options  - doesn't work on a D5 left key)
Lastly, does anyone know why there isn't a 5D center customization button on DJI Go 4.

My setup is iOS (iPad mini 5), current version of DJI Go/Litchi.
