GPS reception, 15 pro max

Foreflight, pilots navigation software. and had the same problem with Maps, or Google Maps…

When flying commercial I still follow what’s going on. No problem with my 12Pro Max, even when having the aisle seat.

upgraded to the 15, window seat, I had no GPS reception for the majority of the flight. Once connection is lost , the 12 reconnects quickly, the 15 fails at that task 100%.

I am trying to find out if my 15 is a lemon, or if this is a more common issue.

thanks for any feedback!
