Realm keeps crashing

When playing on a paid for realm on both the xbox one and Minecraft PE...

Takes forever to join realm. Then when you finally join and start playing, it works for a minute or two then you are disconnected from server. 

If you try to rejoin it brings up error messages saying can't connect at the moment. 

Then when it finally does rejoin it resets the progress to before the crash as if you were never did anything.
