Trying to join my friends Realm that he created on XBOX ONE edition. sometimes I'm able to play without a problem. but then suddenly (like today). it stops registering me breaking blocks, which do happened from time to time but after a moment comes back and i can play again, not today though. i had to restart the game. but when i did it got stuck on "Building Terrain". in the loading screen of the realm.
i tried to reinstall the game, reboot my computer and all that. nothing fixed it.

This has happened before and at first i thought it was my connection that was the problem. but after some research i believe it is not. 

so what can i do. seems like an priority issue you guys should fix is it not? yet I've seen post way old about it. but maybe you just don't care.
