ACCIDENTALLY UNLINKED PLAYSTATION ACCOUNT

you would have to talk to PlayStation support, as far as I know you can't unlink your account. Once you attach an account it's there for life

Hi Arjen,

Thanks for the reply. As you posted to unlink the account you go through the PlayStation settings. We do not handle PlayStation. This is why I directed you to PlayStation support as the PS account is not unlinking correctly.

Thanks,

Brad

Hello,

Please check out this page: Minecraft for PlayStation® FAQ – Home

It states:

Linking a Microsoft account to a Playstation® account

WARNING Once a Microsoft account has been linked to a PlayStation® account, neither the Microsoft account nor the PlayStation™ Network account can be associated with a different account. 

If you choose to unlink accounts, then purchases will be returned to the account which made the purchase. Even after unlinking, Microsoft and PlayStation® accounts can only be re-linked to the original account.

What happens when I unlink my Microsoft account?

IMPORTANT Once a Microsoft account has been linked to a PlayStation™ Network account, it cannot be unlinked without loss of access to entitlements and Minecoins on other platforms. 

According to this thread you can unlink the accounts: Minecraft PS4: Unlinking Microsoft Account - Microsoft Community

However, even if you unlink it, according to Mojang you can only Re-link it to the original account, you cannot link a different PlayStation account to the Microsoft account.

Thank you,
