My little test just now, Goggles 3 and Motion Controller 3
No unexpected braking, flew high and low, straights and corners, sport and normal mode (ignore the 189 warnings re the unbound device, couldn’t be arsed swapping)
Is that behind a big tree?
They weren’t ‘big’ trees, but I was flying around and then between trees with maybe a 10m gap between those on the left and right.
Keep in mind this was in Sports mode, so no obstacle avoidance to detect the trees. And at different times I turned obstacle avoidance off in the goggles menu, just to be sure it really was off.
Now I did wonder if it was related to the downward VPS, and a sudden raised area in that spot, but there isn’t one. Also, later in the video I’m flying at 16m above ground level in a straight line and it was doing it.
I was thinking more about losing signal with the goggles as O4 in CE mode isn’t great behind objects
Stick the ham file in the goggles and test it again
Maybe thats it, mine is 
enabled (legacy from the Avata 2)
Thanks for the advice. But I have no idea what a ham file is.
Use the search 
if you get stuck ask
Are these Goggles 3 or the N3?
If concerned ship it back
This is probably a red herring but worth ruling out: check your Safety settings and the max range/distance.
I had something similar once and it was because I had the range set too short and so it braked as soon as it hit the edge of the window.
Not sure how that would appear in the logs
I had a similar issue today in normal mode but it’s stopped again now
I’ve been in touch with DJI and they’ve had me upload all my N3 goggles and A360 flight logs.
I’ve been informed they will pass them on to their engineers and I should hear something back within three days.
I had it happen in normal mode as well. But I tended to dismiss it, believing it was probably overactive obstacle avoidance.
Which is why I started flying in Sport mode and paying particular attention if the same thing was happening there….which it was.
Good idea, but my max distance has always been set to unlimited and the max height to 500m. Obviously, I don’t fly that high.
Cover yourself for the mountains round Farnborough ;o)
Ironically, it’s the low flying military aircraft you have to watch around here. Some of them definitely below 120m.
An update. I’m still in the process of discussing this with DJI and sending them flight logs. But it looks like more A360 owners are running into the same issue: https://fb.watch/G_HiqeuJHj/
I saw that FB post after reading this thread and I wondered, if it was going to be a common issue.
I assumed (in the case of the OP’ s FB video), that the obstacle avoidance had slowed their A360.
Keep us all updated with DJI’s responses.
