Okok,just dindn't know why 14.0.8.0 was pulled from updater.You can download MIUI 14.0.8.0 manually, move to the new HyperOS (Android 13) build for Poco F3 or even install a port based in Android 14
It's up to you
P.s Dunno much about ports,heard somewhere that are not so reliable driver and compatibility wise
