Sometimes the directional arrow on the screen is facing 180 degrees off during flight, the changes even affecting flight arrow if I lift off from my front yard, or my back yard. Homepoint updates were done before all flights. Until liftoff, arrow alignment is correct, but it goes 180 at actual liftoff. No issues with the flights, just the arrow direction can be disconcerting. Any suggestions out there to cure this? Problem is on both a Standard and a Pro, using a Nexus 7 tablet, a Samsung S5, and S7 edge.
