Where did you purchase your phone and which country are you using it in?
Your screenshot shows a CSC code mismatch.
The original CSC code for your device, S21+ 5G, is MXO = Mexico.
It has since been re-flashed with the generic European firmware, EUX, and is running the old AUJ7 firmware from last year on Android 11.
With such a mismatch, you will not receive OTA, (Over The Air), updates from Samsung or via Samsung's PC suite, Smart Switch.
I am given to understand that you can no longer change your device's CSC code by using sites such as SamKey.
You therefore have 2 choices...
