Pocket Edition Custom Skins Not Working

I have had this problem just going into my own worlds when a skin made on Skinseed or from the internet is used. The error says my skin is "corrupt or invalid" and defaults to an alex or steve skin. It is able to load in but appears blank when it says to select a skin type. There is nothing wrong with my skin formats, PE is not allowing custom skins to be used which makes the game not as sun to play.
