If you haven’t seen the prompt in your News Feed, there’s a simple way to check your account. Facebook’s help center now has a section that tells you whether you or a friend were affected, available right here. >Affected users will be prompted to change app settings, but it’s worth checking over the list of Facebook apps you have to ensure you remove ones you no longer need. Facebook is not notifying individual users of the identify of the friend who used the “This Is Your Digital Life” app, though.
