Note: Selecting "Revoke Access" for Xbox in the "Connected Account" section of bmw service near me will only revoke Xbox's access to your EA information, but your EA account will remain linked to that Xbox account. You will need to contact EA Customer Support to successfully unlink your Xbox and EA accounts.
