Very sorry for the trouble this is causing! When you say that the button is disabled, do you mean that it's faded visually, or just that it doesn't react if you tap on it.

If it's the latter, does the button work correctly if you enable landscape mode (in settings) and tilt the phone on it's side before entering that screen?

We encountered a bug in the French localized version of the app earlier this week; it's possible you've encountered a different case of the same problem.
