It's been like this for a while where everytime i join a server of even start a singleplayer game i always have the default skin and i don't know how to fix it. Everytime i try saving a skin it says it's "Unable to Save" So i am basically stuck as a default skin and so is everyone in every server i joon. I've had this game since 2012 and i just now started playing again and part of the fun in minecraft is seeing everyone's unique skins. Please help
