Hello everyone, I've been unable to install any TestFlight build on my device for over a week. Every build shows "Complete" in App Store Connect, but installation always fails with the same error. I also submitted a support ticket to Apple Developer Support over a week ago but have not received any response. I'm posting here hoping someone from the community or Apple team can help. Error Message "The requested app is not available or doesn't exist" (Turkish: "İstenen uygulama kullanılamıyor veya yok") Environment Device: iPhone 17 Pro Max iOS: 26.4.2 App: Easyway Digital Library Bundle ID: com.abacusai.turkishsocialme.t1777823268 Build Framework: React Native (Expo SDK 54) What I've Tried (Nothing Works) ✅ Multiple builds uploaded (build 4, 5, 6, 7, 8) — all show "Complete" ✅ Deleted and reinstalled TestFlight app ✅ Signed out and back into Apple ID on device ✅ Restarted iPhone ✅ Tried different browsers (Safari, Chrome, Firefox) ✅ Tried Internal Testing — receive email but can't install ✅ Tried External Testing — same error ✅ Tried creating Public Link — same error ✅ Cleared browser cache, tried Incognito mode ✅ Verified Export Compliance (ITSAppUsesNonExemptEncryption: false) ✅ Paid Apps Agreement: Active ✅ Free Apps Agreement: Active ✅ Bank & Tax info: Complete Build Status in App Store Connect Version & Build: 1.0.1 (8) Status: Complete Date Created: May 15, 2026 Timeline May 8, 2026: First build uploaded — same error started May 10, 2026: Paid Apps Agreement activated May 15, 2026: Still the same error after 8 builds Apple Support — No Response Submitted a support ticket on approximately May 8, 2026 Category: App Store Connect & TestFlight Issue: Cannot install builds via TestFlight Status: No response received after over 1 week No case number update, no email reply Questions Has anyone experienced this with a new app on TestFlight? Is there a known issue with TestFlight and new Bundle IDs? Could this be related to the Paid Apps Agreement activation delay? Is there a way to reset the TestFlight state for a Bundle ID? How can I escalate my support ticket if there's no response? I'm completely stuck — I cannot test my app at all. Any help or guidance would be greatly appreciated. Thank you!
