Seen this to be a popular topic lately and just wanted to let everyone know how this video is demonstrating aim assist is incorrect. Aim assist has never worked this way on mobile or other platforms. "Aim assist only pulls when you're moving either your move stick or look stick" - This comes from one of our mobile developers after I showed the video to the team.
The team is going to look to see if anything is wrong with aim assist, but I also reported the issue last month and no issues were found with aim assist. If anything comes out of testing I will let everyone know.
