++please don't mark this as a duplication and actually help me and others on this, it wont let me save my dang skin and its getting really annoying. i want to use my new skin but it keeps saying can't save skin or something like that, please give me some actual information instead of bot replying, and also yes i have checked the search feature and other things related to this issue and i still can't find a solution also idk what these VERSIONS mean but it doesnt have anything to do with that its the damn launcher
