It's uncommon for several reasons: it's not very accessible, its predecessor skeuomorphism (like Win95 style interfaces) was overdone for decades, and it ignores all the reasons we transitioned to flat design in the first place.

>Neumorphism never quite made it mainstream because it comes with its own set of problems. The low contrast does not offer sufficient visual weight, making the experience not accessible. Additionally, it is difficult to determine clickability, as neumorphism is often used inconsistently on nonclickable and clickable elements.

Don't get me wrong, I still like the design and I think it's cool, but I understand the reasons why it never got popular.

Yeah I've heard about the accessibility argument. I tried to mitigate that somewhat with the button designs having a black/while outline (depending on the theme), but I may need/want to add a "high contrast" mode later on.
