Hello, I am looking for help here. My MM crashed (IMO by itself) yesterday into a river. I wasn't able to retrieve it and found this forum where it looks like I am not the only one. I was looking for help in ruling out user error. I am I viewed the interactive flight history on the app and there I am not using the controls to lower the drone and the saved video from the cache shows I did not hit anything. Thoughts on this? Thanks to all! I want to call DJI and be prepared when I seek a warranty replacement.
