No Updates in System Preference?

I was using Big Sur Beta since 11 Beta 2 has been out..

Surprisingly and Annoyingly I was not able to see any updates in system preferences it always says Your Mac is up to date even on Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina Big Sur update is not visible to me which was used to visible in the past.

So I used to download full installer from App Store and reinstalled whole os but it is painfully expensive process if anyone knows what to do please help

Now 11.2 Update is still not visible

I tried full format and reinstallation of whole os all kext and OpenCore has been updated to latest version.. ​
