ENTITY_UNPROCESSABLE.BETA_CONTRACT_MISSING — TestFlight builds show as "Testing" but cannot be installed (internal and external), newly enrolled account

Hi,

We cannot distribute any build via TestFlight. Both internal and external testing fail. This appears to be a server-side beta contract issue on the account.

1. Builds upload and process successfully. All 8 builds show status "Testing" in App Store Connect with 84-90 days remaining.
2. In the TestFlight app on device, the build appears with an Install button. Tapping Install fails immediately with:
   "Could not install [App]. The requested app is not available or doesn't exist."
3. This happens for INTERNAL testing as well, which does not require Beta App Review — indicating the problem is not in the review pipeline.
4. In App Store Connect, the "What to Test" step fails with:
   "There was an error processing your request. Please try again later."

Repeated failures on the beta review submission endpoint:

Failed to load resource: the server responded with a status of 422

Also observed:

404 NOT_FOUND — /iris/v1/appTaxCategories/[app id]
"There is no resource of type 'appTaxCategories' with id '...'"

This is a newly enrolled account; all agreements became Active Oct 19-22, 2026.

• Version: 1.0.0, builds 6 through 15, uploaded Oct 22 and Oct 28, 2026 — all AFTER the agreements became Active
• Processing status: Complete / Ready to Submit
• App Availability: configured, no territories stuck in "Processing"
• Encryption: ITSAppUsesNonExemptEncryption set in Info.plist
• History: First release cycle; app has never been removed from sale

Multiple new builds, removing and re-adding testers, new testing groups, reinstalling TestFlight, verifying Apple IDs match invitations, multiple devices and multiple Apple IDs. No change.

Could the beta contract for this account be re-provisioned on the App Store Connect backend? Per previous threads this appears to require internal action.

This is a server-side issue, not device-side. A sysdiagnose can be provided on request.

Thank you.
