v0.8.1 alpha

I have 3 children, each one has a copy of Minecraft PE installed. THe devices are a Kindle Fire HD (Android), Galaxy Tab 2 (Android) and a Galaxy Tab 3 (Android).
All was fine, but since the game updated itself, none of the devices has been able to connect to another realm (the option is just not present).
I don't feel that any screenshot will do justice, as I can see that this seems to be getting reported by MANY people now.
What I'd like to see happen within the next week, is:

A. Get this issue resolved.
B. Provide a way to revert to the previous "working" version.
C. Return the cost of the product on each device and I will get it uninstalled.

Seems a fair request, as you seem not to be too bothered about providing a fix, and as none of the kids now want to play minecraft, because of this issue that YOU caused, I'd like a return of their pocket money they spent to get this bug ridden game.

Thankyou

A very disappointed set of users
