Bugs and no iphone 5 screen support

This is a very cool game. I have the board version, which is awesome. This allows me to practice anywhere. Which is usually on the toilet.

There a some bugs in the game.
-Pieces disappear randomly
-some pieces wont move
-the multiplayer does not seem to work most of the time

Where is the iPhone 5 widescreen support?
