No. You should not have to relink the remote controller after it has been linked.Do I have to press the linked button on machine every time I want to fly?
Litchi and all other 3rd party DJI GO alternatives cannot be installed on the P4P+ remote controller.I have a p4p + and I've been told some 3rd party apps might work and some won't. What the consensus. Especially concerned with Litchi.
