Facebook crashes

Dear Community,

well as we know Facebook tries, since many years, to relaese a usable iOS app, but since some minutes they reached their personal ultra fail. The app just crashes if I open it. I made no changes on my iPhone. No iOS update & no Facebook update.

Is this a Facebook server prolem, because I delete the app, shut down the iPhone 4S (iOS 6.0) and reinstalled the app. No changes.

Any ideas? Do you have the same problem?
