After many years without any connection issues, I am having the same connection problems in my plane.
Configuration A: ipad mini2 OS 12.5.7 / TRX1500 with AirConnect / Sky Demon 3.16.10.373 not connecting
Configuration B: ipad mini4 OS 15.8 / TRX1500 with AirConnect / Sky Demon 3.16.10.373 not connecting
Configuration C: ipad mini4 OS 15.8 / TRX1500 with AirConnect / AirNavigationPro connecting without any issues
My conclusion: Problem seems to be in the SkyDemon camp
Question: Is there any solution in sight?
