Packer_Backer8 Just to clarify, the background service may keep running because part of the EA app is still active in the background, even if it looks closed. Clicking the X button minimises the app to the system tray, and in some cases, it can stay running without any visible window, which causes the background service to restart.
If you're using the EA app through the Xbox app on PC, a related process might also be running. Right now, that process should not restart the background service after it's shut down, but that could change in future updates.
To fully close everything, try quitting the app from the system tray or using the Task Manager to ensure no EA processes are still running.
I’ve also shared your feedback about the X button not fully closing the app. It’s a valid point and something others have raised too.
