Problems playing online

I'm having problems when I'm entering the world of realms or some other mobile game, I'm entering the world, the world doesn't load and I can't do anything, and for the other players I'm in the world but standing still, at first I thought you problem in the internet connection, but this only happens only when I enter the realms server or some version of mobile that when I enter the PC and consoles my game works well, I would like to know if there is any way to solve this problem because I I bought realms and would love to play in the world
