Bought a cute texture pack and it won't load

My daughter plays Minecraft and I finally gave in and bought her a texture pack. And it doesn't work. Actually I bought it twice as I bought it on another device to see if it worked there. All the devices are linked to my account. So I wasted money on the same pack twice and it still doesn't work for my daughter.

please fix this ASAP. She is very sad now. Thank you

i really don't know the version or anything. It's minecraft for iPad
