Infinite laserflip on chum bucket doesn't work ?

Same for me, xbox

UPD: after few restarts and few attempts got this registered. Pretty sure I got it earlier with more clean landings tho...

I also had to do it twice before it registered 

I did it twice so far and it’s not registering. Even recorded it just for proof to show this trash doesn’t work. 

I just cheesed it; did the infinite flip from the highest building, then glided onto the roof of the chum bucket; that triggered it just fine.
I think the issue may be with where you land after the trick, perhaps the coding for the spot boundaries isn't quite right?
