If push notifications aren't working, check that the service worker is registered correctly and that notification permissions are granted. Verify the implementation of the push notification service.

Push notifications are a key feature in keeping users engaged with your application, and resolving issues with them is crucial for maintaining user interaction. If your app's push notifications are not functioning as expected, start by checking that the service worker is registered correctly. The service worker is responsible for handling push messages, so any issues in this area can prevent notifications from being delivered. Ensure that users have granted notification permissions; if permissions are denied, notifications will not be shown. Review your implementation of the push notification service, ensuring that the appropriate API keys and endpoints are configured correctly. Testing the push notification flow in different environments is essential; for instance, notifications may work on some devices but fail on others due to platform-specific restrictions. Additionally, consider implementing logging for notification delivery attempts to help identify issues with message delivery. Encourage users to provide feedback about their notification experience, which can inform future improvements. By systematically addressing these aspects, you can enhance the reliability of push notifications in your application.
