I am the owner of a realm and every time I try to get into it, it gets stuck on the "Joining Realm.... This may take a few moments" screen, and after about 4 or 5 minutes it shows a screen that says "Failed Attempt to join realm, try again later". I backed up the realm earlier today a couple hours before this happened, but other than that i haven't done anything that might cause this.

Edit- This bug has been happening for everyone, here's the tweet mojang gave out;
