I was successful to get a 3 day unlock code for a restricted area. I got to fly and got my photos on day 1. The problem was that my drone was not able to fly anywhere else “cannot take off” for days 2 & 3. Question, How do I remove or cancel an unlock permission code from my unit once it has been used. I tried toggle green button to off, no help. On day 4 all was OK and drone flew as normal. Any suggestions appreciated
