The glitch, in question, appears to only be effecting me. Other people have problems similar to this, but this situation is rather different, since it would say that I already have my Microsoft Account linked to my PlayStation Network Account, despite that it isn't. And as I mentioned in the summary, I tried making a new account and email to link my accounts, and yes, it did not work. I hope you are capable of looking into the problem I am currently having, since this has been happening for quite a while. I remembered that I once signed one of my accounts into Minecraft, and it worked. But now, it has forgotten that I use that account, and despite me making myself another account with my other email, it still does not work. It only works on my old edition of Minecraft, but not on the current version (Version 1.16.4). I hope you can help me with my current situation.
