Hey guys. Thanks ahead of time for any time taken to help me out. I just bought a smart controller and when I go down to fly at the beach I must request permission from the landing field closeby. It keeps telling me I must have internet connection in order to do it. So, I hook my phone up to the hotspot but it doesnt stay connected once I go back to the other screen. Does anyone know what to do. I am so frustrated.

You can self unlock from your PC before you head out, just make sure you sync the controller on wifi before you go.  A unlock lasts 3 days - https://www.dji.com/uk/flysafe/self-unlock
