On two occasions I have attempted to fly in controlled zones and needed to unlock the drone. Both times I was connected to the cloud with my smart controller tethered to my iphone. Signal strength was fine. The message on the remote was I was in a controlled zone and need to unlock the drone And click here to unlock. I follow the instructions, but nothing happens. In Both occasions I had to apply to unlock the drone from my desktop. I seem to recall a similar problem with unlocking when I first got my mini 2. Has anyone been successful in the field with unlocking Their Mini 3 Pro drone?
