Stuck at level 4

So I have been doing dnb for 15 days now. Not completely in a row, as I have missed probably 4-5 days, but pretty consistent.

I got up to level 3 pretty easily, but have been stuck trying to get past level 4 for what feels like the entire time I have been playing.

Level 3 feels so easy, but as soon as I get to level 4 it's like I have completely forgotten how to keep things in my memory.

I have tried to stay away from the strategy's people talk about, as I read that the best way to do is to just play and figure it out.

I'm just at this wall. And I have only passed it once getting to level 5, which I was completely terrible at and got sent back down immediately.

The only time I passed level 4 it felt like I was just doing it completely on intuition. It almost felt like I was guessing.

On level three everything is very clear, I remember it all almost perfectly. But level 4 it's just feels like a completely diffrent game.

Do you guys have any experience with this? Will it eventually just click one day?

It just feels like a brick wall.
