Well plenty of crashing going on and not much to say about that.
The one thing that is consistently wrong is zooming in and out, the map is fine but the route does not. Scale is off and doesn't stay connected to the proper waypoints. The only way to fix it is shut down the app and restart it. Ugh, it is getting old while in flight.
Using latest version and iOS. iPad a couple of years old.
Is it a known bug?
