== Special Notes regarding iOS17 or TVOS17 ==
Beginning with iOS/TVOS 17, Apple is adding several requirements for App developers around tracking, use of Identifier For Advertisers (IDFA), and certain system APIs.

This requirement entails users manually opting in to declare all domains employed for tracking purposes, which includes the collection of IDFAs (Identifier for Advertisers).
Currently, even if users choose not to opt in for tracking, it's essential to note that our Nielsen Digital SDKs continue to carry out measurements and transmit data without relying on IDFA. However, this new privacy measure introduced by Apple necessitates that we bring this development to your attention, as it could potentially impact your Nielsen measurement and tracking for iOS app usage.

In order to minimize the impact, we are asking that clients do the following:

* '''Do not declare the Nielsen imrworldwide.com domain in the privacy manifest.'''
* Update to the latest Nielsen SDK release >= 9.2.0.0 when compiling your app for iOS 17.
