Hi there, I received a brand new Anafi after switching under warranty due to a sudden crash. I am a professional videomaker and Anafi crashed with no reason during a flight. Now, after unboxing and battery charging, I tried to switch it on but nothing happens: after pushing (shortly) the switcher battery leds turn on for a few seconds and the drone doesn't power up.... what can I try to do? I tried both with new and "old" batteries". Thanks.
