Phantom 3A using a iPad Mini 4. If I plug in the iPad to the RC prior to starting the RC and aircraft it says Disconnected in upper left corner of the screen and no picture. I then have to unplug and replug and it works fine. If I land and power off only the aircraft to change out a battery it will say Disconnected again upon powering up the aircraft requiring me to unplug and replug the iPad again. I don't remember it doing this when I first got it. I've only had it a month
