Hi, I’m seeing a strange TestFlight issue.
My builds process successfully in App Store Connect, appear in TestFlight, and are assigned to internal testers, but installation fails immediately with:
“The requested app is not available or doesn’t exist.”
What I’ve verified: • builds are processed/completed • apps are visible in TestFlight • internal tester groups are configured • agreements/banking/tax are active
This affects multiple apps in the same developer account.
The issue started after adding a widget extension and moving to a new Swift-based workflow, so I’m trying to isolate whether this is: • signing/provisioning/entitlements • widget extension misconfiguration • or a backend issue on Apple’s side
I’ve already contacted Apple Developer Support and submitted Feedback Assistant reports.
Has anyone seen this exact behavior before?
