Minecraft Realms textures don't load on Android

I don't know if it's a texture problem, a Realm bug or multiplayer servers because when I load the world it doesn't develop the textures well. I can see the other players, but they can't see me, the blocks that I extract don't stay in my inventory, my life is lowered apparently by Mob attacks which I can't see or interact with them. It is also impossible for me to use the chat, as my messages do not appear, and when I die (as I indicated by Mobs), it takes time to regenerate to the point that I have to close and reload the world. I have a 20mbps internet speed, I never had this problem before with any version of Minecraft. This problem only occurs in Realm, because when playing alone everything is fine.
