@Tenly: I have P3P and have not had any major issues at all until today!!
I updated to the latest fw that came out today, both Ac and the batteries were all updated.
I went out about 3000feet at 390' up. All of a sudden I got zero satellites and then shortly after that the signal bars dropped to 0 for both the video and radio signal and the signal lost and rth initiating warning came up. Immediately after I clicked on "rth now choice", the app became unresponsive, latest iOS on iPhone 6+. I waited about 2 minutes and when I couldn't see the p3 I hit rth button on RC, it started its normal beeping and couple minutes later I saw the p3 coming home, I cancelled rth and landed manually. I then shutdown the app and restarted it but still no connection, so I unplugged lightning cable and replugged it back, the app then connected to the p3. This flight was I middle of no where,! I thought well, maybe "whatever" happened, so I put I second battery and went up 10' and out about 5', satellite, radio and video signal greyed out and app became unresponsive again, this time I unplugged and replugged the cable and the app then got video and signals back!! All very odd, never had any of these types of issues before today, after the latest fw update!!
Will try again tomorrow with different cable and then different device,
air2,and see if problem disappears.
