First, I tried to add skin with Google photo app (this is OS standard gallery app) and it makes the same error "This is not a Minecraft skin silly".
After seeing this issue, I installed Google gallery (Gallery Go) and adding skin is succeed.

I have the same problem. All enchanted armor is not rendering correctly. I tried changing the skin and setting combinations, and resetting it, but nothing changed. Resource packs and behavior packs are not used. This issue did not occur on Windows.
