Hi 5e8wwo74of4b,
Typically, when this issue occurs, it's due to age restrictions limiting the account from connecting online. Tends to happen when the date of birth input states you're a minor.
The support team is needed as updating account information requires verifying you are the owner, making that request, which we can't do through any other channel. After that stage is passed, they'll then ask you for proof of age to ensure you're not a minor chancing their arm to get access to features currently not available to them (read for more on that). There'll be set criteria as to what's accepted to prove that, but once it's been verified, they'll update the DOB for your account, and you should be able to use the 'EA Connect' option from there.
