Does anybody know why?

Thank you for contact us! I'm Anderson, an Independent Consultant and a Microsoft user like you.

good evening

Unfortunately, the Microsoft account only has linked social network accounts, game accounts such as ubsoft, epic games, psn, are done in reverse, that is, the platform account is linked to the microsoft account, and microsoft does not have access accounts owned by other companies.

In your case, only Playtstation can help in this process since Microsoft does not have access to either the process or the information.

Gotta love it when they use the "friend excuse".

as long as the monitor has an HDMI in you should be fine.

Staring at some of the monster wall statue things on each side unlock a few more hidden koins. Just stare at each one for about 5-10 seconds and it will auto lock onto it. Dunno which ones they were though...forgot sorry. But I know for sure there's atleast
one on each side.

Just keep playing. Do ladder matches on beginner and get some flawlesses plus babalities. That's an extra 1,500 koins. I had something like 350-400,000 after story mode and only unlocked a little over half the Krypt, I think.
