I recently got the M2E and had a flight in an authorization zone. Went through the DJI self unlocking just like i have numerous times with my Inspire 2, but I can't get it to work. When I check my NFZ applications in the Pilot app it shows up and says the unlocking is valid, but when I connect to the aircraft it disappears. I have double checked the flight controller SN and I'm not sure what else the problem could be. Has anyone else experienced this issue?
