So is there anyway to do a quick file transfer between my mini three pro and the newer DJI RC?  Do I need to have a memory card installed in the controller also for this feature?  I see them doing it between the drone and the iPhone using the DJI fly app. But there is no such a such option with my mini 3  and my newer RC controller.   It just won’t do it.
