As JimmyHAD has said, there are MANY variables. It could be any of them. When I had issues when beginning(different than yours, but still issues) I kept the lather and razor the same and only change ONE thing each shave. It gave me a way to zero in on the problem. If that didn't work, I changed the lather, but kept everything else the same, AND if that didn't work I changed the razor....

I hope you get my drift which is there is no magic bullet.

FWIW, I think you also need to give some thought to whether you really need ATG or just want it and whether BBS is a reasonable expectation for your face. I've been shaving for more than 50 years, and I have a very rough beard. I have never been able to go ATG with any razor of any type....my face doesn't like it. When shaving with a SR I try all kinds of angles/passes and am very successful at getting a DFS everywhere, every time. Sometimes afterwards I rub some section of my face and think I could have tried something a little different to get "perfection". Then when I shave with a DE (usually because I don't have time or concentration for the SR shave) I realize my SR shave, overall, was better and maybe I'm setting an unreasonable expectation for my SR shaves. Just something to think about, especially while you're early in the SR journey. Then there's the Gold Dollar thing...I won't go there.
