I can't create a realm

I have been trying to create a realm for me and my youtube subscribers, but it will not let me. Everytime I try to create it, it says "Your Purchase succeeded,but we couldn't create your realm right now. We will create your realm as soon as possible. Check back later on this device" but it still hasn't created the realm. Then when I try to make a new one, it goes to the box companion app, and it gets pretty far then it says, "looks like you already own this, go to My games or My library on your home device to download it. But nothing is there that has to do with realms in My games and My Library. I was hoping that someone could help me as soon as possible. Thank You.
