EA App Won't launch Sims 4, says "Standard Edition accessed through Steam"
Sims 4 updated to the 6/6/2024 update and now will not launch through the EA App where I play and have purchased DLC. I have already cleared the cache and restarted my computer.
@therealbigjerm Try removing the game from your Steam library, then clearing the App's cache:
