This will sound really weird but you need to caress the button.
I've tried different timing options in practice mode and the one that one is to gently push it. It's actually one of the best uses of pressure sensitivity I've used in a video game.
For a bullet pass, mash it hard. For a lob, tap it fast. For a touch pass, gently push it.
In the famous words of the man in black, "Gently. GENTLY!"
Dont tell me you gotta hold the r trigger as you hit the button for the receiver i know that! The thing is the shit is so inconsistent you may as well flip a coin and say a prayer that the game actually registers it as a touch pass. Who tf was asking for them to remap controls? NO ONE!
