@MojangSupport I was having an issue with my friends realm only to find out it's definitely not just us. I'm sure you guys are working rapidly on a solution to the Realm problem.
I'm sorry for any trouble you're having right now! It's currently a temporary issue we're looking into. I would check back in later on and keep an eye out on https://twitter.com/MojangStatus for any possible updates. Thanks for your patience! ^AS
