You know it easily when you let Origin or Steam or Epic Version updated the game when you opend the related App where you have purchased the game/key, Mate. You can also right click your FIFA 23.exe in your FIFA 23 Folder. Than click on the bottom - Properties - next click - digital Signature -
There you see the date of your game Exe last time updated. Should be first of Februaury - so yesterday. If there is another date you are on a previous TU Version.
Anyway, if you wish to play on TU 7 just let your Client update the game if they prompted when you open your Client app. That´s it. On what Client you are running your FIFA 23? Orign, EA App, Steam or Epic Store??
