As of this morning, Mojang opened up more Realms servers to be claimed by Minecraft Pocket users. The problem though is that Realms looks to be very glitchy and has a ton of problems.
Some people have managed to lay claim to multiple servers, while others cannot log in to their server at all. This has left a lot of hopeful pocket edition fans frustrated at Mojang for the mess that MCPE realms has turned out to be.
More updates will come as the situation with Realms continues.
