Your puzzles are literally higher than mine. Well, I kind of just okay the first move that comes to mind without calculating in puzzles. Ignore that.
I think 2400 is a good puzzle rating. Perhaps what you need to do is learn some basic positional concepts and try out longer time controls. I recommend 15|10 or 30 minute rapid games. They will give you enough time to think.
I’m 2,400 puzzles but can’t break 1,000 in Blitz.
Every game is the same - the same generic openings until somebody forgot what to memorize.
Every game is the same - somebody wins a pawn early on and then trades everything until their one pawn in the end game wins.
Everybody is horrible and has no clue what they’re doing , yet everybody can play the same openings.
Watching videos does nothing. Puzzles does nothing. Trying some cool tactic does nothing.
There’s literally zero progress. Somehow, after 200 hours of effort, in the exact same rating as where I started.
Fun game.
