Flabby XX1 chain

My chain looks flabby when on the smaller sprocket.
Not sure it was like this before. You can see the picture.

From the second sprocket and up, the chain get straight.

I don't have a tool to check the chain wear.
But used the 12" trick, and have 305.5mm instead of the planned 304.8mm.

Should I remove one link? Or tighten something on the derailleur?

It looks like you need to remove a link.

Did you follow the SRAM setup instructions when you first installed it or did you use it at the length it came?  I needed to remove 3 or 4 links if I recall correctly on my 256 with a 32T and X01 cassette.

After removing a link, it looks much better now. Thanks.

I followed SRAM instructions initially, at least I think.
As I'm fiddling so much on my bike. I'm surprised I didn't see it before.
