Hi--new to drone operations and loving my Evo Pro II! Quick question: After requesting and receiving controlled airspace authorization, when I'm done flying---say 25 minutes and I'm done with the shooting, though I requested and was granted 60 minutes--do I need to do anything? Cancel the request? or anything? or just leave?. I was using AirMap tonight and I had 10 minutes left but wasn't sure what I am supposed to do. Thanks!
