Hello, I am experiencing a persistent TestFlight installation issue affecting multiple unrelated apps under the same Apple Developer account. For all affected apps: Builds upload successfully to App Store Connect Processing completes normally Builds appear in TestFlight Internal and external testing can be enabled Public links generate correctly However, when attempting to install the app via TestFlight, the installation fails with the error: “The requested app is not available or doesn’t exist.” This occurs: For internal testers For external testers Across different Apple IDs Across different devices With newly created apps After incrementing build numbers After re-uploading builds After signing out/in of TestFlight After regenerating provisioning profiles After creating entirely new app entries The issue currently affects: • TubeChat AI – Apple ID 6752591427 • Vibex – Apple ID 6756860663 • vigilAI – Apple ID 6757738356 Since multiple unrelated apps are impacted in the same way, this appears to be an account-level or App Store Connect backend issue rather than a code signing or project configuration problem. Has anyone encountered a similar situation where TestFlight distribution fails across all apps within a developer account? Any guidance would be greatly appreciated.
