Whenever i hover over a cheat to click it, it says use_hotkeys_to_enable_cheats. And i then press the hotkeys but nothing happens. Yes this is for every game.
Can you post screenshots?
You need to launch the game via the Play button before you can activate cheats.
Also the game needs to be legitimately purchased from the relevant store. Cracked games are incompatible for the most part.
Please post screenshots as asked above so someone can assist you further if needed.
