When I start the DJI GO APP in selects automaticaly P4 Advanced, and I can not switch back manually only if I close de app!!
And when I click enter device it says "Aircraft Disconected''
I cant connect to the aircraft anymore...

That's because the app isn't detecting a connected craft - it displays the P4A by default, I believe. Android or iOS? If Android, is another app not taking the USB port as a default?

Anyway, others will have a view here, but I always power on in the order craft-RC-GO. That way everything can be detected as needed.
