Re: APEX ISSUE
Typically when we see situations where you no longer have access to prior currencies and unlocks, that means an account has been unlinked or you may be playing on a different platform.
If you've unlinked any accounts in the past, re-linking the same account should give access back to your content.
Please reach out to support if you run into any trouble with that process.
If you're playing on a different platform but haven't unlinked an account, keep in mind there's currently no cross-progression in Apex. That should be coming later this year, but until then you'd need to continue playing on the same platform to have access to those prior unlocks.
