Is my K1C (2024) compatible with CFS?

Hi, I just bought a K1C, didn’t know that are two versions of it. I came back to 3d printing from like 8 years ago, and everything is new. I just saw that CFS is compatible with K1C, but in the firmware page, the last update to the firmware of my machine (I understand that the motherboard from my machine is CR4CU220812S11 because the firmware 1.3.3.46 and the S/N 10000787785B324JANV), but the multicolor system firmware is for CR4SU200382C13. Is that relevant? Or I’m ok if I buy CFS?.

Don’t buy unless you’re prepared to return it.

Why? What’s the problem? As I understood from some videos, the original K1C didn’t have a problem like the K1C 2025,

Realistically: I’m spending more time fixing my printer than printing. It is very common that printer UI stops responsing. Simply darkened and print don’t accept any button push. Really annoying when you want to pause print for some reason. No way how to do it.
