Production "Request a Test Notification" returns 4040007 while sandbox test and production notification history succeed — is the production URL gated on first release?

Our approved app is held at Pending Developer Release because the production App Store Server API cannot find our notification URL, even though the Production Server URL is saved in App Store Connect. The failure has been constant since August. On October 20 we ran two tests that isolate it, and we would appreciate someone from App Store Server engineering checking the request UUIDs below.

What works

• Sandbox Request a Test Notification, same In-App Purchase key, same bundle ID, same URL string as Production: HTTP 200, token issued, Get Test Notification Status reports sendAttemptResult SUCCESS 280 ms later.
  • 2026-10-20 16:31:13 UTC · request UUID ad1708d2-8536-4204-9a7b-32ded5800d48 · correlation key VULQRUUFGZBAJGT3GLPNLAANJA
• Production Get Notification History, same key: HTTP 200 (0 records, app not yet released).
  • 2026-10-20 16:40:08 UTC · request UUID 7aedd431-fcf1-b104-42cd-17cc599425e4 · correlation key PLW5IMP46GYQIQWNC7GFTFBF4Q

What fails

• Production Request a Test Notification (both api.storekit.itunes.apple.com and api.storekit.apple.com): HTTP 404, errorCode 4040007, "No App Store Server Notification URL found for provided app." No testNotificationToken is issued, so Apple never contacts our endpoint.
  • Most recent: 2026-09-30 11:25 UTC · request UUID 22a1e218-4cdc-3577-9e18-3e25caf64052 · correlation key EKQ6EGCM3Q2XPHQYHYS4V5SAKI
  • Earlier: f0cf352f-828e-fd40-8c14-2000fb8181e3 (Sept 23), 74a8bbbd-cd43-a18b-c4ac-bba619232d1d (Sept 14), 412d6c9f-511c-4402-ba18-d33fcda1b916 and 4f88fc30-3a4c-b7da-5d67c2f88570 (Sept 4, two different keys)

Already done

• Production Server URL verified as saved in App Store Connect; removed, saved, re-added, waited, retested. No change.
• Reproduced with Apple's App Store Server Library (Swift) and with a minimal client.
• Feedback filed: FB24641446. Developer Support escalated the case to engineering on September 18; no engineering response yet.

The question

In thread 806452 an App Store Commerce Engineer wrote that production API access is unlocked once an app has a release in production. Our production history call succeeds for an unreleased app, so we cannot tell from outside whether the notification URL lookup behind /inApps/v1/notifications/test is gated on first release.

• If it is, we will release today and retest; a one-line confirmation would end a seven-week hold.
• If it is not, the production notification URL record for this app appears to be missing or unreadable, and we would ask that it be inspected and rebuilt.

Happy to run a fresh reproduction in any time window and post the UUID. App Apple ID 6793806173, bundle com.haullynx.app.
