Hey folks,
If you had progress on two separate EA accounts, that cannot be merged or transferred to another EA account.
Cross Progression allows you to access the content on a single EA account with the platforms connected to that EA account, and cannot be used to transfer progress to a different EA account entirely.
If you've unlinked a platform from one EA account and linked it to another, you will be able to access the content on that newer EA account with any linked platforms, but those will not bring any content from the original EA account.
If you lost progress due to the unlink and were wanting that to be restored, you'll need to re-link that platform to its original EA account.
