Restore Custom Classic Skin Support on Xbox Bedrock

Custom classic (PNG) skins previously worked on Xbox Bedrock when uploaded on a linked mobile or PC device, but this no longer functions in recent versions (e.g. 1.21.x), showing errors such as “Local skin could not be loaded.” This change limits player creativity and identity, especially on multiplayer servers that disable or restrict Character Creator / Persona skins. In those cases, players are forced to use default skins even if they have a custom classic skin available on other Bedrock platforms. Custom classic skins still work on Bedrock for mobile and PC, so restoring optional support on Xbox would improve consistency across platforms while giving players more freedom of expression. Restrictions such as size limits (64×64) and format validation would be reasonable to maintain performance and safety. Please consider bringing back custom classic skin support on Xbox Bedrock, or providing an official alternative for players who prefer classic skins on servers that do not allow Persona skins. Thank you for reading.
