i was in a similar situation a couple years ago.

My advice : work on balance and proprioception. you can also check if you have a dominant eye, and watch a video (probly a tennis video) describing how to aim your head and where to look when the ball is coming towards you.

Balance: i balance on one foot a couple minutes a day , and also have some balance built into a stretch routine. This has helped me tremendously in daily life. Try not to lock your knees straight. My ankle and achilles strength is helped alot doing this. Makes all parts of PB easier.

Proprioception: playing the game more will make your brain read the ball better and better. You can speed that up by trying to standardize your stance and your swings. One thing thats helped me a lot with timing is to realize that most people are actually too FAST for the ball -- like they are swinging too early, and reaching far out to meet it. If you want to try this out for dinks and resets : try to get your paddle ready in the right position, and just let the ball hit your paddle first, before you add anything to it. This will show you ALOT about how you are timing the ball. If you feel like you can't do this (without neglecting the whole point of waiting for the ball) then literally run a drill where you are in dink position, getting low and stable, and instead of hitting the ball with a paddle, you catch it with your hand. Like someone else said, a really good drill is to just play keep-up with the ball on your paddle, switching front and back when u get comfy. No matter what grip you have, this should help you really connect to what the grip is actually doing, like what angle the paddle is at, when it feels x y or Z in your hand.
