Old console account gone and replaced with a new one

@ReggieVeggieTTV 

Usually in cases like this, there could be 3 possibilities as to why this is happening.

Based of the thread from @EA_Mari : https://answers.ea.com/t5/Cross-Progression/Now-that-Cross-Progression-is-here-what-you-need-to-know/m-p/13260639#M4188

"Not all of my accounts were shown on the account merging screen:

Only accounts that were linked to the EA account at the time of receiving Cross progression are eligible to be merged together. 

There are a few exceptions for accounts that will not be merged:

• Accounts that are linked to a different EA account
• Accounts that are banned
• Secondary accounts that were created after October 26th 2023"

Obviously, I would assume that neither of your accounts have been banned or made a secondary account after October 26th.

So you must have unlinked your main platform from your main EA Account. In this case since you can't unlink your platform, you can contact EA Support and speak with an advisor to assist you in linking the right platform. The link I provided here will show you steps on how to contact them: https://help.ea.com/en-us/help/faq/using-ea-help/

Let me know if you are successful in making the changes you need.
