Neo went haywire and flew away instantly

I was on a small island that I was looking to explore and I put the Neo into follow mode. Instead of taking off from my palm and hovering until I started walking, it immediately flew off to the right of me at a high speed and above the water almost as if it was doing an orbit, then it just lowered and went into the water. I do have DJI care and reached out to them, but this seems more like a malfunction than what it does user error. I’ve watched the footage a handful of times to make sure I had it in the proper mode and I didn’t miss a step, and it seems like the drone itself just went nuts after immediately taking flight. I’ve requested for the file to be reviewed and for the Neo to be replaced through at DJI’s expense.

Would love to hear everyone’s thoughts. I feel like I got lucky with having my action 4 recording at the same time to actually capture what happened. And I had to laugh at my commentary as I was frustrated and could see it happening and there was not much i could do since I didn’t quickly enough.
