Update the `Info.plist` file by adding the `NSUserTrackingUsageDescription` key with a custom message explaining IDFA usage. Link the `AppTrackingTransparency` framework. During testing, remember the IDFA ATT dialog appears only once unless the app is uninstalled and reinstalled due to the one-time authorization request. The form is available if the authorization status is `ATTrackingManagerAuthorizationStatusNotDetermined`.\n"]]
