I want to use my Microsoft account on my ps4 on Minecraft but it’s linked to my old ps4...

I have linked my Microsoft account to my PS4 account in order to play cross platform minecraft. The issue is that I would like to play cross platform with my brother, who is playing using my Xbox One. My microsoft account is now associated with
both my PS4 account and Xbox Live account, which means that we share a gamertag. For this reason I cannot add my Xbox account as a friend on Minecraft and cannot play cross platform. I attempted to resolve this issue by unlinking my Microsoft account from
my PS4 account but this did not resolve the issue. I was unable to link a different Microsoft account to my PS4 account, a message informed me that my account was already linked to another and could not be linked again.

Please can you make it free Minecraft Minecraft store PS4

also I have forgotten the email so I want to know what Microsoft account is linked to my ps4 account so I know what email to use when trying to link my account to play Minecraft.

Is there any way possible to be able to use my Ps4 mojang/Microsoft email on my new ps4 with the same Email that I've been using. Because I want to use my Email to sign into my ps4 minecraft.

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!

I want to disconnect my Microsoft account from my PSN account but Minecraft on PS4 says its permanent, is there a fix for that?
