🛠️ Issue: “Notifications and PWA”

Before anything you need to know that Sngine supports 2 kind of notifications

• Browser Notifications.
• OneSignal Push Notifications (via Service Workers)

1- Browser Notifications

✅ Works only if:

• The browser page is open and active (or at least the browser is running).
• Notification permissions have been granted.

this will not work when the browser is closed because it lacks a Service Worker and Push API subscription, which are required for true background push support.

2- OneSignal Push Notifications (via Service Workers)

Yes, push notifications can be received even when the browser is completely closed, as long as:

• The browser must not be uninstalled or blocked by the OS.
• The PWA is installed or the user previously allowed notifications via Service Worker.
• The OS itself permits background push (modern desktop and Android browsers do).

⚠️ Limitations:

• iOS (Safari) support is limited: On Safari, push notifications work only for installed PWAs (iOS 16.4+).
• On desktop browsers, notifications show even if browser UI is closed, because the Service Worker runs in the background.

That’s it.

Happy Sngine 🙂
