Since we configured App Store Server Notifications V2 on 15 October 2026, every notification for our app is recorded as TIMED_OUT, with the attemptDate equal to the signedDate (same second), and no HTTP request ever reaches our server. 35 Sandbox notifications (TEST, SUBSCRIBED, DID_RENEW, EXPIRED): one attempt each, TIMED_OUT. 2 Production TEST notifications: retried 5–6 times over a week, all TIMED_OUT. Our endpoint is public, TLS 1.3, valid certificate, answers in < 400 ms, and processes the signedPayload correctly when we POST it ourselves. Today we pointed the Sandbox URL to a webhook.site URL and requested a test notification: TIMED_OUT within 10 s, nothing received on webhook.site either. The app (com.virginactive.revolution, appAppleId 1620160868) was transferred to our current developer account on 2 October 2026; notifications have never been delivered under the new team, so we suspect a server-side state issue after the transfer.
