Pair the app with your account
After installing, the app must be linked once to your account.
Open the app: a pairing code shows on the sign-in screen.
Sign in to your account in the browser and enter that code.
The app connects automatically; the code is single-use.
This walkthrough does not apply to the games, which have neither an EA Nexus account nor a pairing code: Colosseum, Castle, Floor, Orchard
