New Ota-Update not working on MIUI 11.2 20.1.21

[Sick0015]

So i have a Xiaomi Redmi mi9t/K20, currently with MIUI 11.2 20.1.21 Beta.
The ota Update tells me i have the newest Version, which i doubt.
Which Version can I easily Update to and how?
Because in the Ota-Update screen if i wanna select a package it says no app can do that Action.

Any help would be highly appreciated.
Thanks

Download the latest version and install it via TWRP
