The Vision function on chess.com that Julian mentioned is interested, I actually didn’t know that existed. The only thing about that is when I first learned the coordinates it was easier to learn them in relation to the pieces on the board initially. For example, I knew that the e file was where the kings were, and the d file where the queens were. So if someone moved the king pawn up 2 squares, I knew it was e4 for white and e5 for black. Or when the white bishops come out all the way I knew it was Bg5 on the kingside and Bb5 on the queenside. The best way to pick up on this is to force yourself to notate some games without looking at the coordinates. I’d do it playing against bots or something so you don’t have the pressure of a real game. At each move, ask yourself what you think the coordinate is, then check if you got it right and make a mental note. It’s a bit tedious but you’ll start to pick up on things pretty quickly.
