My custom skin shows in the Minecraft launcher but not in my singleplayer JAVA world. The default skin of Steve is what shows in-game instead. This has persisted for about 6 months now and I've tried logging out and logging back in to the launcher numerous times since then. I recently migrated to my Microsoft account and it's still a problem even though my skins came over just fine in the Launcher. I've checked that my XBOX PC settings are all set to "allow." I spoke to 3 people in support before they decided it was a probably a bug to report. Please let me know if you need any further information. Thanks
