I have a Flydigi Wee 2 that worked great for a while. But recently some of the buttons have stopped working. They're simply not recognized by the app. Specifically, the B (right), Y (top), and start buttons don't register. This happens both when using the generic gamepad mapping or when attempting to make a custom mapping - I can't map those buttons because nothing happens when I press them.

I was afraid the controller was dying but the buttons work in other games and apps. What can I do?

I am in the beta; is there a way to roll back to the stable release without leaving the beta? I don't know for sure when it started happening because I don't use the controller that often.

EDIT: It looks like some connections in the controller are just failing. It works when fully extended (for landscape mode) but not in portrait mode or when the phone isn't inserted.
