Hi everyone, We've been stuck on this issue for several days and would really appreciate any guidance from anyone who has encountered this before. Issue Our app uploads successfully to App Store Connect, appears in TestFlight, and the build status is Ready for Internal Testing. However, every internal tester receives the following error when trying to install the app through TestFlight: Could not install . The requested app is not available or doesn't exist. Environment Apple Developer Program: Individual Distribution: Internal TestFlight Framework: React Native (Expo SDK) Build Service: Expo EAS Build Submission: Expo EAS Submit Platform: iOS What we've already verified The app builds successfully. The IPA is signed successfully. Build upload to App Store Connect succeeds. Build processing completes successfully. The build is assigned to an Internal Testing group. Internal testers have accepted the invitation. The bundle identifier is correct. Distribution certificate and provisioning profile are valid. We generated fresh builds and submitted them again. We recreated the App Store Connect app and submitted a new build. We also regenerated signing credentials where applicable. The issue persists across multiple builds. Additional Information During eas build, Apple successfully authenticates, registers the bundle identifier, creates the distribution certificate and provisioning profile, and the build completes without errors. eas submit also completes successfully, and the build appears in TestFlight. The failure only occurs when attempting to install the app from the TestFlight app. Error Could not install . The requested app is not available or doesn't exist. Has anyone experienced this issue recently? Is this likely a TestFlight/App Store Connect backend issue, or is there any App Store Connect configuration that we may have overlooked? And this is our active case id for the support: 102930164003 Any suggestions would be greatly appreciated. Thank you!
