How do you change your animal skin. It says I have it but when I try to put it on it doesnt work. ?

It maybe a bug. But don’t worry i’ll help you. Tap the skin that’s unlocked and don’t tap any other skin. And stick with that skin.

I had the same problem you just get out of the game it comes back asking you to select animal and single player multiplayer etc. just press select animal and choose.
