This does not fix the issue. I've tried making sure the app and secondary services are up to date, that I'm connected to the internet, uninstalled and re-installed both the EA app and the game and I still get stuck with error 500 and the same message as others have pointed out when trying to launch a game. "We've noticed your computer is currently offline. To activate your game on this computer using your EA Account, you'll need to connect to the Internet."
There is a problem with the current version of the EA app not with people's hardware or OS configuration.
For what it's worth I'm trying to launch a game through my Xbox Game Pass account. Not sure if the connectivity between the Xbox app and the EA app has anything to do with it.
