Thanks - good to know. Begs the question why would you ever want to log out. But my use case is probably different: I'm using a dedicated smart controller.In order to be able to log in to your DJI account in either the GO4 or FLY app your device needs to be connected... once logged in you can proceed flying off-line & still be considered to be logged in by the app, you don't need to be on-line all the time.
If you log out when your device is off-line you can't log in again & will face the height and distance restrictions until you can get on-line & log in again.
