Interesting, that has not been my experience with the app... for instance, if I submit a flight plan that enters controlled airspace for a non-LAANC participating airport the app will either debit me clearance or go into a never ending loop. That’s my experience in IOS iPhone XMax.That's not necessarily true since that will also happen if you attempt to start a flight in a no fly zone.
BTW, I actually fly with my CS and not my phone.
I have gotten clearance for that particular area through FAA DroneZone and this is not reflected in AirMap.
