Push Notifications Trouble Shooting


In the fast paced world of mobile applications and website, push notifications have become an indispensable tool for user engagement. However, the road to effective push notifications is not always smooth, and troubleshooting issues can be a tough task. In this guide, we’ll explore common push notification problems and provide practical solutions to ensure your messages reach your audience easily

Common Push Notification Problems

Check Permissions
Firstly, one of the most common issues users face is not receiving push notifications due to wrong permissions. Make sure your app or website prompts users to grant the necessary permissions during the on boarding process. Additionally, guide users on adjusting notification settings in their device or browser settings.

Verify Server Configuration
Secondly, push notifications rely on a robust server infrastructure. Confirm that your server is rightly configured to communicate with push notification services like Firebase Cloud Messaging (FCM) for Android, or Apple Push Notification Service (APNs) for iOS. Double-check API keys, certificates, and other authentication details.

Handle Token Refreshes
Thirdly, Device tokens, which identify a user’s device for push notifications, may change over time. Ensure your application or website handles token refresh rightly. Update your server with the new token to avoid sending notifications to out dated or invalid URLs.

Optimize Payloads
Push notification pay loads contain the information shown to users. Optimize your payload to avoid common issues like truncated messages or missing data. Be mindful of character limits, especially on iOS, and structure your payload according to platform specific rules.

Address Device-Specific Challenges
Different devices and operating systems may exhibit unique challenges. Stay informed about plan updates and changes to notification handling. Regularly test your push notifications across various devices and operating system versions to identify and address compatibility issues.

Consider Doze and App Standby Modes
Android devices, in particular, have power saving features like Doze and App Standby that can affect the delivery of push notifications. Test how your app behaves in these modes and implement strategies like Firebase Cloud Messaging’s high priority messages to over come these challenges.

Monitor Delivery Metrics
Leverage analytics tools to monitor the delivery performance of your push notifications. Track metrics such as delivery rates, open rates, and conversion rates to identify patterns and potential issues. Use this data to refine your notification strategy and improve user engagement.

Implement Retries and Exponential Backoff
Network issues can sometimes disrupt the delivery of push notifications. Implement retries with exponential backoff to ensure that even if a notification fails initially, your system will continue attempting delivery at intervals, slowly increasing the time between attempts.

Test in Real-world Conditions
Conduct real world tests to work in various cases, such as low network connectivity, background app usage, or intermittent device access. This helps uncover potential issues that may not be apparent in controlled testing environments.

Stay Informed and Update Libraries
Lastly, keep abreast of updates from push notification service providers and the platforms you support. Regularly update your server libraries and client SDKs to benefit from bug fixes, improvements, and new feature that can enhance the reliability of your push notifications.


Since troubleshooting push notification issues requires a proactive approach, attention to detail, and a commitment to continuous improvement. Therefore, by addressing common challenges, optimizing your configuration, and staying informed about platform updates, you can ensure that your push notifications are a powerful tool for engaging and getting back users.
