Hello,
New individual developer account (enrolled October 2026). My first iOS app cannot be tested via TestFlight.
-
Internal testing: builds 1.1.2 (16), (17), (18) and (19) all show "Testing" in my internal group. Two different internal testers (Account Holder and a Marketing-role user) on two different iPhones (iOS 26) get:
"Could not install. The requested app is not available or doesn't exist."
App Store Connect shows 2 invites but 0 installs for every build. -
External testing: when I add build 19 to an external group and press "Submit for Review", App Store Connect says:
"There was an error processing your request. Please try again later."
Already checked: membership active, Free Apps Agreement active, export compliance answered, build metadata "Validated" (SDK 23F81a, min iOS 15.0), pricing Free and available in Türkiye, testers accepted the invitations, TestFlight reinstalled, devices restarted.
Developer Support case: 102998773608 (opened October 16, no reply yet)
Feedback: FB25298826
Screenshots attached: (1) the install error on iPhone (Turkish UI: "Could not install ASG – Afyon Scooter Derneği. The requested app is not available or doesn't exist."), (2) the App Store Connect error when submitting build 19 to the external group.
I don't have a Mac, so I can't attach Xcode device logs; builds are made with Codemagic.
Could someone from Apple please check whether a TestFlight/beta setting is missing on my account? Thank you.
