Hi, new to group. Have been flying my Mavic Pro for 2 years in and around my own yard and house and nearby park. Yesterday my app asked me to update my GPS so I did. Now I cannot fly in my own yard because it determined that I am in a No Fly Zone due to a local airport about 5 miles away. I called DJI support and they tried to walk me through the unlocking process but he was hard understand due to bad connection and foreign accent and I thought that I had done everything properly but my controller still would not let me fly. When it asks for S/N does it mean for the aircraft or for the controller? Any help out there? Please?
