It doesn't need to be patched, it needs to learn how to defend and not rely full on AI when defending. You need to timely switch the player (you should put on manual at least the player switching). Anyhow, you can use legacy defending if you like the FIFA defending of old times. And it's always like this the first days until people learn the new defence.
I'm in Division 2 in seasons and every game is very high scoring. No one can defend. It's not a case of not being able to time it in my opinion. In 2v2 i'm ranked 6th in the world and seeing all the best players not being able to defend.
This game has problems. Fixable problems but problems all the same.
