GKGameCenterViewController *gameCenterController = [[GKGameCenterViewController alloc] init]; if (gameCenterController != nil) { gameCenterController.gameCenterDelegate = self;//not available for tvOS gameCenterController.viewState=GKGameCenterViewControllerStateLeaderboards; [self presentViewController: gameCenterController animated: YES completion:nil]; } Any advices? Thank you!

Dear All Though my app doesn't implement ATT and has declared Data Not Collected in the privacy section, Apple has rejected its update for many times, saying The app privacy information you provided in App Store Connect indicates you collect data in order to track the user, Apple also says: If your app does not collect user or device data for tracking purposes, please update the information you provided about your app’s privacy practices in App Store Connect. The point is that the app does not include ATT framework nor the AdSupport framework. It is a paid app and does not include ads sdks either. I have repeatedly requested Apple to tell me where my app had declared that it would collect user or device data, Apple never answered directly, and finally suggested:Review developer documentation for the AppTrackingTransparency framework. See Frequently Asked Questions about App Tracking Transparency. Ask fellow developers and Apple engineers a question in the Apple Developer Forums. Since the app does not implement ATT at all, I come here to ask for your help. Thank you in advance.
