Haven't flown my mini for a while. When I finally got it out today the DJI Fly app prompted me to log-in or else my distance and height would be limited. Since I didn't log in my distance and height were indeed limited. Is there any way to turn this feature off? I'm using an old iPhone as my controller and it doesn't have any cell service. Not a problem when I'm at my house flying and I'm connected to my home WiFi to get logged in, but when I'm heading out into the field, this could potentially be a problem. Any advice to how to fix this would be greatly appreciated. Thanks so much.
