"Something's not working with the Facebook for iOS app.
If something's not working with the Facebook app for iPhone or iPad, first make sure you have the most up-to-date version of the app. To do this, go to the App Store on your iPhone or iPad and update the app. If there's a newer version of the Facebook app you don't have yet, it'll be listed there for you to download.
