I have had my phantom 3 professional for roughly 6 months and relatively no problems. Got the bird out this weekend to fly and cannot connect to the DJI go app on an iPad 3 mini. Tried 2 other iPhones, 6+ and iPhone 6, and iPhone 5S and still no luck. Have tried updating firmware on the quad copter and looks like successful. It appears the remote will not update when I plug in USB flash card reader, lights do not change colors. The remote is connecting to the aircraft and will fly, just can't enter camera view on the app. Any help is much appreciated? Thank you. Carl.
