The Skin picker Doesn't work, By It Doesn't work I mean the Confirm Button Doesn't Un-Disable (Video showing What happens), So I can Pick a Skin But I can't click Confirm, So I have To close then Open Minecraft To get The Skin To load, This also Happens In-game. So I cant Change Skin In-game Without Exiting and Re-opening Minecraft. If you can Fix It, Thanks.
