The quad only hovered, wouldn't follow me after the set up was applied. My ipad mini 3 is wi-fi with cellular, so it's my understanding I would have gps although I don't have a SIM card installed. How do I activate the ipads gps? Perhaps a related issue, when I try to set a new home point I always get the new home point wasn't recorded message. Am I missing a setting on the mini 3 to enable cellular (with out a SIM)? Thanks
