Dear Apple Developer Technical Support Team, We are currently integrating Apple Search Ads attribution (SKAdNetwork / AdAttributionKit) for our application, but we have been unable to receive any attribution callbacks from Apple. We would appreciate your assistance in diagnosing this issue. App Information: App ID: 1531290216 Bundle ID: com.volvapps.tk2.cn Callback Endpoint: Our server endpoint for receiving attribution postbacks is: https://volvgames.com/.well-known/skadnetwork/report-attribution Issue Description: We have conducted multiple tests under different scenarios, but in all cases, our server has not received any callback from Apple. Test Scenarios: ① Xcode Installation Test Built and launched the app directly via Xcode. Called the following APIs within the app: SKAdNetwork registerAppForAdNetworkAttribution SKAdNetwork updateConversionValue:value Result: No callback received on our server. ②On-Device Developer Mode Test (AdAttributionKit) Enabled AdAttributionKit Developer Mode on a physical iPhone. Configured a development postback using the app’s Bundle ID. Used either the provided developer postback URL or manually entered our endpoint. Created and triggered the postback via “Send Development Postback”. Result: No callback received. ③Additional Attempts Modified the callback URL from: https://volvgames.com/.well-known/skadnetwork/report-attribution to: https://volvgames.com/ Repeated tests under both Xcode and Developer Mode environments. Also attempted triggering postbacks after calling the attribution APIs within the app. Result: Still no callback received in all cases. Additional Question: We understand that certain files may be required for review or troubleshooting. However, we were unable to find where to upload attachments when submitting this request. We would like to provide the following files for your reference: info.plist AdAttribution.mm Could you please advise how we can submit these files to assist with the investigation? We would greatly appreciate any guidance or suggestions you may have regarding this issue. Please let us know if further information is required. Thank you for your support.

Hi, I’m stuck with submitting a Game Center leaderboard and wanted to ask if others are seeing the same issue. My setup: App is already live on the App Store Game Center capability is enabled Leaderboard works perfectly in TestFlight (scores are submitted and visible) Problem: When I try to submit the leaderboard for review, I get: “A Game Center enabled app version must be added for review.” This is confusing because: The app already includes Game Center The app is already approved and published Apple documentation says Game Center components can be submitted without a new app version I also tried recreating the leaderboard and checking all settings, but the issue persists. Is this a known App Store Connect issue? Or is there something I’m missing? Thanks!

Updated my app to include turn-based matches. Beta testing through FlightTest and all was well between iOS 18.x and 26.2 devices. One beta tester upgraded to 26.2 during beta testing and now when the MatchMaker VC is opened, it does not show existing matches. Worse, he can create new matches and play his turn, but the new match won't even show up in MMVC, even after opponent takes turn. My app has been reviewed and is ready for release, but I'd like to know how to solve this before I release. He has tried re-installing the app, including an updated FlightTest version that is the same as the about-to-be-released reviewed version.
