Hi excitedbanana,
Sorry to hear you're running into an account linking limit error. I can understand why that would be confusing, especially if this is your first time trying to link these specific accounts.
The "linked too many times" error usually refers to the lifetime limit of platform accounts that can be associated with a single EA Account. To help you understand the rules and risks associated with this, I recommend reading our official guide on linking and unlinking platform accounts here:
Link your EA Account to your console, Steam, Twitch, and more
For your account's security, we can't check an account's linking history or make any changes to these limits here on the forums. This is something our support team will need to investigate for you.
Once you have reviewed the guide, you can contact our support team by scrolling to the bottom of that guide page and selecting the Contact Us option.
If you have any trouble with that, you can also use our direct webform to submit a case:
I hope the team can help you get this figured out.
