On my long cross country trip (65 hours in the last two weeks) I did find two things that seemed like bugs.
1. Leaving the airport area
At least 5 or 10 times while I was in cruise flight, sometimes no where near an airport and at least a couple thousand feet agl, I would get an alert that I was leaving the airport area. Something didn't seem right about that. Couldn't figure out precisely what conditions triggered the notice.
2. Dim route and airplane
A few times, in the middle of a flight, the route and airplane display would go dim, so dim as to be unreadable. The display of the background map remained normal. Nothing I did got the purple line or the position marker to return to normal. Eventually, I just had to shut down the application and relaunch it, which solved the problem. Couldn't figure out precisely what conditions triggered this one either.
Best,
Paul
