In DJI Fly  1.4.12 iPadOS 15.0.2, DJI broke the compass.
Usually you can select to lock the map pointing north, or have it point in the direction you are facing.
Regardless of seeing the locked "N" indicator...or the compas needle, The map is locked to north.

This feature to unlock the map is needed so a pilot knows where to point the antenna.

Hello there pmshop. I am sorry for the trouble this has caused and thank you for reaching out. I will cascade these information to the designated DJI department for attention. Again, I am sorry and thank you.
