Ever since I bought my P4P 2 Year’s ago, the small circle in the lower left of the screen that indicates the relative direction of the bird to the magnetic heading. Now, for some reason, the “N” is in the 270 degree location on the circle. The bird flies correctly relative the “N”, but I want the “N” back where it has always been in the north up position. Tried everything I could to change it, but no deal. When I first fire up the tablet, controller and bird, it is correct. When I select “normal flight mode” with the blue icon, the next screen rotates the circle to “N” pointing west. Please help.
