I was flying my mavic today. And it disconnected for the first time ever. Freak me out pretty bad I had no control at all. I shut the controller off and started it back up again. Reconnected and it was fine. Then I landed it and took off again after checking some settings and it did it again this time it was over quite a bit farther away. It automatically return home which is fine. Could someone tell me what is causing this it has never done it before
