I was going to wait a few days to update, but found that the Pilot app on my iPhone 6+ had already been automatically replaced by DJI GO, so decided to go the rest of the way. Upgraded aircraft per directions, no apparent problems and result file shows "success". Put in my other battery and repeated above. Started the DJI GO app to upgrade the RC per the directions. At first I had to go through the "connect your aircraft" exercise. Then it connected and I could see on the iPhone what the camera was seeing. Message in app said RC upgrade needed. Then it said it couldn't upgrade RC through app, had to use other method. Used a USB stick and loaded P3S_FW_V01.03.0020.bin onto it. Put in RC and started it. Upgrade progressed as described and result file says "success". Now, the status bar in the app says "Disconnected". I've waited about 15 minutes for connection, and tried several times restarting everything. Even shut down and restarted the iPhone. I can start the motors by CSC and tilt the gimbal with the RC dial. But nothing in the app. I did not have this problem before. Any help would be appreciated.
