It does not let me add addons or upload worlds to my Realm.

When I put a addon in my Realm or upload a world and then click the arrow to exit that screen in the top left it says "All Done! 0.00MB-----._MB Lets Go!". After I click lets go it keeps repeating that and doesnt stop until I close my game. 

At the end of it all it doesn't load the world or addons.
