On PC, I have my uncharged melee assigned to 'G'. I also assigned that button to my finishers. On PS5, I tried to make the uncharged melee and the finisher be a single button press of 'X' but it does not work properly. Character just hits uncharged melee even when finisher is available. I had to make it a long press of 'X', but I thought it was worth asking.
