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.

【背景】 現在、各広告実績(コスト、クリック数など）とCV実績（Adjustローデータ）を紐付け、広告ダッシュボードを構築しております。 iOSアプリキャンペーンにおいて、AD名での紐付け(SQL上でのjoin)が必須となり、ご質問させていただきました。 【質問】 SKAN側の仕様について、計測時SKANからMMP側にデータを送信しているかと思います。 この送信データに、ADG名、AD名は付与されているのでしょうか。 Adjsut担当者様より、リファレンスは無いがポストバック値にはある、とご説明いただきました。 SKAN側でリファレンス等あればご教示いただけますと幸いです。 また、SKAN4.0からは source-identifier がポストバックデータに含まる認識ですが、 この4桁の数値からADやADGを特定することは可能なのでしょうか。 MMPや広告主側で各ADにsource-identifierに紐付けは不可で、媒体側で自動発行される認識をしており、発行粒度/規定も媒体ごとに異なっていると理解しております。 ご返答いただけますと大変ありがたいです。 ▼参考リファレンス https://developer.apple.com/documentation/storekit/verifying-an-install-validation-postback#3592477

We’re testing SKAN postbacks via AdAttributionKit but aren’t receiving any requests on our server even after generating development impressions and triggering a postback. Setup: Domain: https://linkrunner-skan.com Configured in Info.plist as: <key>NSAdvertisingAttributionReportEndpoint</key> <string>https://linkrunner-skan.com</string> <key>AttributionCopyEndpoint</key> <string>https://linkrunner-skan.com</string> Apple automatically appends the .well-known paths: /.well-known/private-click-measurement/report-attribution/ /.well-known/skadnetwork/report-attribution/ ATS diagnostics for the domain: PASS for all tests (TLS 1.0–1.3, PFS disabled, arbitrary loads allowed, etc.) Both .well-known paths are publicly accessible and return 200 OK Testing Flow: Enabled Developer → AdAttributionKit Developer Mode on iOS (15+) Followed Apple’s official guide: Testing AdAttributionKit with Developer Mode Generated test impression using: createAdAttributionKitDevelopmentImpression implemented in SKANManager.swift Called Postback.updateConversionValue with lockPostback: true Created Development Postback from Developer Settings Waited 30+ minutes while intercepting server requests (proxy + backend logs) What We’ve Tried So Far: Confirmed ATS compliance with nscurl --ats-diagnostics (all PASS) Verified .well-known paths are accessible publicly without redirects Tested endpoints manually with a POST request – server responds 200 OK Confirmed Info.plist entries exactly match Apple’s required keys Double-checked iOS device is running iOS 15+ with Developer Mode enabled Repeated test flow multiple times with fresh impressions and postbacks Waited up to 1 hour for postback (in case of delays) Issue: No POST requests are being received from Apple to either .well-known endpoint, even though the setup appears correct and ATS tests pass. References Used: Configuring an Advertised App Generating JWS Impressions Question: Has anyone faced a similar issue where AdAttributionKit Development Postbacks are not firing despite correct Info.plist setup, ATS compliance, and reachable .well-known endpoints? Any insight into possible missing configuration steps or testing nuances would be greatly appreciated.

How would one interpret guideline 5.4 VPN? It states: "Apps offering VPN services may not sell, use, or disclose to third parties any data for any purpose, and must commit to this in their privacy policy" Does that mean you cannot integrate Ad SDKs inside apps offering VPN functionality? Or does this only apply VPN Traffic? So using third party Ad SDKs like Admob is fine, as long you don't share any VPN traffic data? (e.g. Admob runs inside the App Process/UI, but doesn't run inside NEPacketTunnel) We have a similar case (and couldn't get clarification from App Review so far)
