11.1 is the UI version, 12.3.6 is your FSD version... chances are you're on 2024.3.25 or 2024.8.x, both of which are FSD v12 but UI v11 software versions. The latest version is 2024.14.x which is FSD v12 and UI v12. You're not that far behind and will probably get an update within the next few weeks. Totally not confusing at all
