I have searched this problem before and there was only one similar post. It was however, not resolved. My problem is that on 1.16.2 my skin shows up as an Alex to me and my friends even though I selected a new skin in my skin tab and on the minecraft website. The other post was told to wait a few hours and I waited 24 hours but no change. I don't know if this is a new bug or not, but please help.
