Describe the bug

Admin → Push → "Send a test push notification" reports "Your push was sent to 1 device" but no notification is received on Android or iOS. Nothing appears in Android notification history (Settings → Notifications → Notification history), confirming the notification never reached the device at the OS level.

Desktop notifications work correctly.

Steps to reproduce

1. Deploy Rocket.Chat 8.3.2 via Docker with gateway.rocket.chat as push gateway
2. Log in with the official Rocket.Chat Android app (4.71.2) and iOS app
3. Verify push tokens are registered: db.getCollection("_raix_push_app_tokens").find() — tokens exist with appName: chat.rocket.android and chat.rocket.ios
4. Go to Administration → Push → Send a test push notification
5. Interface reports success ("sent to 1 device") but no notification arrives

Conclusion

The Rocket.Chat server correctly sends push requests to gateway.rocket.chat. The gateway returns a success response (server reports "sent to 1 device") but the cloud push counter remains at 0, indicating the gateway accepts the request but does not forward it to FCM (Android) or APNs (iOS).

The issue is inside gateway.rocket.chat — nothing on the self-hosted server side can resolve this.

No repository file or test is identified. Start at the Administration → Push test flow and the gateway.rocket.chat request, then inspect the registered tokens in _raix_push_app_tokens and the rocketchat_notification_queue behavior. Done means the gateway processes the request and a test notification reaches Android or iOS.
