iTunes app rejected: app uses the iOS Advertising Identifier but does not include ad functionality

Hi,

my latest app version just got rejected for referencing

class: ASIdentifierManager

selector: advertisingIdentifier

framework: AdSupport.framework

without showing any advertisements. From my understanding they are referenced by the Facebook SDK to "Attribute this app installation to a previously served advertisement", which I checked when submitting the app version to iTunes. I do not serve ads inside the application and have no plans to do so. Anyone with similar experiences? Because the only solution seems to remove Facebook SDK which is no option.
