Achivement armour bug

I have been playing on a world with my friends on my ios device. In this world, I have full netheright which should give me the achievement that it had on my iPad, and it did give me the advancement. However, I just recently bought the game on my galaxyA12 android phone which means I am playing a completely new game called "Minecraft for android". This means that all my advancements are gone however that is not the problem. Whenever I join the world(still wearing the full netheright) it doesn't give me the advancement.
