changing custom skins does not work

Hello there, I recently found a quite annoying bug while play Minecraft Bedrock Edition on my iPad Air.

I had a Christmas skin and since Christmas is over I wanted to change it. I downloaded a new skin and tried it... I realized that the skin did not change.. I tried many times..it was still telling me to choose between slim Christmas skin or the same one but a bit bigger (as always) while I was trying a new one.

I would really appreciate if you could try to fix that bug. Thank you so much for your comprehension.

            Have a nice day,
