Hello - I just installed the Autopilot app and I have a question...hopefully someone knows. I use an iPhone 7 plus that does not have service (old phone). I briefly went into the Waypoints section and it pulled up the map where I am. I was on wifi. I turned wifi off to simulate me being in a field somewhere with no access to wifi and it would not pull the map...no service I get it. Are you able to pull down a location offline maps to use this app? My main purpose of buying this is for when I am on vacation where service would not be available.
