My Air 2S lost signal in its return to home. I was unable to restablish control and drone contact. I disconnected and reconnected phone and control cable in hopes of establishing a signal...negative results. I lost my new drone...just like that. I have owned three different DJI drones (Mavic Pro Plantium, Spark and Tello) prior to my Air 2S. I was excited with the purchase my Air 2S. It took me a year and a half of savings for this drone.
