This issue has been going on for a week now, and I thought it was just with my internet at first.
Whenever I depart from and airport and try to enable AP+, it works, but it does not show up on any trackers, for example, waypoint or infiniteinfo. However, when I come back into the flight, even if it’s 1 minute after and then enable AP+, it shows up.
So, only the first time when I enable it, it doesn’t show up, but the second time, it does.
