Phantom 4 issue, on my last flight I had the video downlink disconnect, and gps indicator showed "disconnected" but I still had control of drone and was able to fly back and land. But now when I try to set up again it just shows aircraft status as disconnected, and video telemetry is blank. Tried rebooting, checked cable connections, different startup sequences but still no camera view coming through to my iPad, or iPhone 6. I also get a pop up notice saying " this device may not be supported " but I'm using the same device I used for first 6 flights with no problems. Any ideas on what's wrong or how to fix? Thanks
