Custom Skins don't work.

Custom skins don't work, while choosing them they show as Steve or Alex, not the real skin, I took a stab at reinstalling the application and clearing cache, nothing works. I additionally saw that this is a truly basic issue on MCPE that custom skins don't appear, and you for the most part need to code a skin pack, which is actually a major exertion for a minecraft skin. If you don't mind fix this. Thanks!
