Sorry for my late reply! Have been going nose-to-grindwheel on the new RealPlan feature.
I checked your log from email, and it contains this line that is culprit:
[Error] : FlightPlan failed to Save(): /storage/9C33-6BBD/Android/data/iFly.GPS/files/iFly/#FlightPlans/KVLD to KLAL.ifp, System.UnauthorizedAccessException: Access to the path "/storage/9C33-6BBD/Android/data/iFly.GPS/files/iFly/#FlightPlans/KVLD to KLAL.ifp" is denied.
For some reason, Android is denying iFly access to the Flight Plans folder. Did you recently upgrade your OS? (i.e. some sort of security patch, that changes file access rights?)
You have Android 7.0 - you might try googling that OS for setting application privileges, and see if there is a user setting per application.
I'm sorry about this inconvenience and the bad timing!
