Theres no one fix, but maybe just playing more otb would help a ton. one thing you can try is setting up a real board at home and playing your online games on it. yes, you’ll have to move both sides yourself, but it really may help you get used to the physical pieces and the 3D perspective, doing puzzles on a real board is great too, it may train your eyes to spot tactics the same way you would in an actual game? thats all ive got
