It appears that I am encountering the same problem that some others are having with Air 2 and DJI Fly. Since day one, I have not been able to make the flight attitude indicator work as it is supposed to do. My graphics always show up in red with a slash drawn through them. Google shows that quite a few others are having the same problem with their Minis and Air 2s. I have tried calibrating the compass in the drone and my smart phone (Galaxy S9+). Occasionally, if I power up the drone first and then the controller, the graphics will flash white for just a second or so...and then go to red. I normally see 13-18 satellites when flying.
I realize that I can get the drone home safely by flying the map; but that isn't the point. I just don't like operating any piece of equipment with a known fault....especially when the cause of the fault seems to remain a mystery. I'm really not expecting to find a solution with this post; but perhaps if DJI sees enough complaints about this situation, they will develop a firmware update to correct it.
