Description
Telegram fails to deliver real-time visual banners or lock screen alerts. However, the background layer is functional: the app icon badge count increments instantly in real-time. This issue is isolated strictly to Telegram.
Expected Behavior
When a message is received, a visual notification banner, audio alert, and lock screen alert should trigger simultaneously alongside the app badge update.
Actual Behavior
The app icon badge updates instantly (proving the APNs payload arrived), but no visual banner, lock screen notification, or audio alert is triggered until the app is opened.
Steps to Reproduce
- Close the Telegram application completely.
- Send a message to the device from a separate account.
- Observe the Home Screen: the app icon badge increases immediately, but no visual banner or sound triggers.
