I can sign in into my microsoft account on my PS4, but i can’t see my world or my friend’s realm. Very strange.

As i said to someone else If you go on your PS4 MC then got to settings, profile, then while logged into the microsoft account you dont want, go down to Unlink Microsoft Account. It sadly doesnt work for me
and says maybe check internet connection. Tell me if it say the same for you

Yes, I get the same error message (check your internet settings) when I try to unlink my sons minecraft account that is connected to his PS4. By accident, I linked MY microsoft account to his (PS4) minecraft account. Is there a way to reset this? Please!
I really want to play minecraft with my son!
