Try a different USB cable.Don't buy a pixel 6 or 6 Pro if you hope to use dji fly app with a mini 2 .... all the controls work but you get NO video on the app it's been reported to dji but no response other than use a phone from the list of known working phones ...
Do you already have a Pixel 6 ?
Who tested it first?
(Otherwise how fond are you of it?)
