As the Phantom 4 manual states, I always turn on my remote controller first, then power up the P4. I already have my tablet turned on and connected to the controller. Usually if all goes as normal, the DJI Go app starts up on its own when I power on the hardware. But sometimes after turning on the controller then the quad, the Go app doesn't doesn't automatically come on. On those occasions, I then open the app myself, but it doesn't show that the P4 is connected. I then have to turn everything off and start over until it does see a connection. Am I doing something wrong? Thanks for any help or advice.
