Remove Minecraft PS4 account.

I managed to do it by removing the game from my PS and installing it again. This allowed me to sign into my Xbox account on PS4 minecraft

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

Hello, In order to fix this, you'll need to find the Microsoft account that you used the first time on Minecraft for PS4, it does not matter if you create a new Microsoft account because is the PS4 account the one that's linked to a specific Microsoft
account. If you don't remember which Microsoft account you used, you can go to Mojang support for them to check what's the Microsoft account that's linked to your PS4 account for Minecraft.

Still cant sign in to my mircosoft account on my ps4 for minecraft

When on Minecraft on the PS4 you should have the option to sign into a Microsoft account.
