Specific App Issues
Some Apps may begin to exhibit incorrect behavior, or could stop functioning with your device altogether.
In this case, it is important to verify that you have the latest version available for your app, and that it is compatible with your device OS.
Some apps may no longer support your OS, or could need to be updated before functionality returns.
To verify your app version number, simply open the app in the Settings menu, and the version number is below the App name.
