Hey there, 

I did accidentally connect my ps4 account to a false Microsoft account. 

I did use the "delete connection to microsoft account" option several times, but it doesn't work.

I did delete my whole saves after doing this, I did quit and relaunch, I did connect and disconnect sereval times but I did never manage to get this working. I did search my ms account if there is a page where I could disconnect but wasn't successful either.

My opinion is that it's broken and doesn't work. 

If I could help just tell me how. 

Thanks in advance

PS4 says it's version minecraft 2.06

P. S. It is broken since the bedrock release on ps4. I'm trying it now an then again, but still no change.
