I got LAANC approval to launch in a NFZ at 50 ft. When getting the approval, it asked for Aircraft; Mavic Pro; Timer..set for 1 hr; Battery, set as Mavic Pro; and that was the end! No way to get off that page to go back to Go4 App. Tried to fly; rotors would not start saying I am in a No Fly Zone. So what is the solution for this.
