Aim Assist nerf season 17 on consoles

I noticed this as well, in game and tested in depth in firing range. 
tested across all sim input styles (classic, linear, etc), and 1-3x scopes.

effectively, at short to medium range, if you use the right stick on ADS to a target and you cross the body of that target, AA is removed. You can stand there and wait, hands off the controller, and 2 minutes later the target will not have it. 
This is also happening in game, I tested it out on an AFK player in TDM. I was able to remove my AA by manually crossing the body of the player with the right stick at all.

When you cross the player and leave the AA zone, you see the camera even out and the aim speeds up. The problem is coming back to the player, it never re-grabs. Once it’s gone, it’s gone.
