I’m another user experiencing this. I am using an iphone 6s. I have been caching using the official app for the last two years without major issues but in the last two weeks the needle when in compass mode has been pointing in completely the wrong direction, 180 degrees to where it should be. The distance to the cache is fine and this is now how I navigate, just keep walking in the direction opposite to the needle and watch the metres count down. Cachly does not seem to have this issue on my phone so its an app specific issue.
