PS4 issue

[XiRon]

You can also play on ps5 but it needs to be the same playstation account, I think this is a playstation issue not square.

You can contact square and ask them to unlink your older ps4 account and link it with the new ps4 account but you may have to buy the game again.

I figured I'd have to rebuy the game bc new library.
Ok.
If I did this, where do I go? Is there a number I call or email I send?
