I have been experiencing a signal loss when flying my P3 Pro, I'm using an iPhone 6 Plus, with the DJI Pilot app connected to my remote transmitter via USB cable. I will start everything up as normal get, the green bar at the top of my screen showing safe to fly GPS. I will fly in some cases not very far away and it drops the connection with the app. I can still controll the P3 but cannot see anythin on the camera. Many times once I land or get close it will reconnect, other times I will need to land and turn off the remote and restart it and I will get reconnect. very frustraiting!

Has anyone had this problem? Help!

Use an apple USB cable and see if that helps.
