Troubleshooting Guide – Why are Your Push Notifications Not Working?




Push notifications play a crucial role in engaging users and driving app adoption. They allow app developers to send timely and relevant messages to their users, keeping them informed and re-engaged with the app’s content. However, it can be frustrating when push notifications stop working, hindering the app’s effectiveness and user experience. In this blog post, we will address the common reasons behind push notification issues and provide actionable troubleshooting steps.

Understanding Push Notifications

Before diving into the troubleshooting process, let’s first understand what push notifications are and why they are essential for app engagement. Push notifications are messages sent by mobile apps to users’ devices, appearing in the notification center or on the lock screen. They can provide valuable information, such as news updates, reminders, or personalized offers, keeping users connected to the app even when they are not actively using it.

Push notifications are a powerful tool for improving app engagement and user retention. They increase the chances of users returning to the app by reminding them of its value and providing timely updates. Additionally, push notifications allow developers to communicate directly with users and deliver personalized content, enhancing the overall user experience.

Common Reasons for Push Notifications Not Working

There are several common reasons why push notifications may not be working as expected. Let’s explore these issues and provide troubleshooting steps to address them.

Incorrect Permission Settings

The first step in troubleshooting push notification issues is to check the permission settings on the device. Users may have inadvertently disabled push notifications for the app or denied the necessary permissions during the initial setup. To verify and modify the permission settings:

  1. Go to the device’s settings.
  2. Navigate to the app settings section.
  3. Find the app in question and ensure that push notifications are enabled.

If push notifications are disabled, users can toggle the switch to enable them. It’s worth noting that the steps may vary slightly depending on the operating system of the device.

Background Refresh Disabled

Background refresh is another crucial setting that affects the delivery of push notifications. When background refresh is disabled, the app cannot receive updates in the background, potentially preventing push notifications from being received. Users can follow these steps to enable background refresh:

  1. Open the device’s settings.
  2. Go to the app settings section.
  3. Find the app and ensure that background refresh is enabled.

By enabling background refresh, users allow the app to receive updates even when it’s not actively in use, ensuring the delivery of push notifications.

Device-Specific Issues

Push notification issues can also stem from device-specific factors, such as differences in push notification implementation between operating systems or specific device settings that affect their delivery. Let’s address some common problems for specific operating systems and provide troubleshooting steps:


iOS uses Apple’s Push Notification service (APNs) to deliver push notifications. If push notifications are not working on iOS, users can try the following steps:

  1. Ensure that the app has the necessary certificates and provisions to send push notifications to iOS devices.
  2. Check the device’s internet connectivity to ensure it can connect to the APNs.


Android devices use Google Cloud Messaging (GCM) or Firebase Cloud Messaging (FCM) for push notifications. If push notifications are not working on Android, users can try the following steps:

  1. Verify that the app has the necessary permissions to send push notifications.
  2. Check that the device has a stable internet connection to receive push notifications.

Server-Side Issues

In some cases, push notification issues may be caused by server-side problems. Let’s explore a couple of common server-side issues and their potential impact on push notifications:

Connectivity Problems

A stable and reliable server connection is crucial for successfully delivering push notifications. If the server is experiencing connectivity issues, push notifications may fail to reach users. To diagnose and resolve connectivity problems:

  1. Check the server’s network connection to ensure it is stable.
  2. Test push notifications on different devices and platforms to assess if the issue is specific to certain scenarios.

Server Misconfiguration

Misconfigurations on the server can also interfere with the delivery of push notifications. Common misconfigurations include incorrect certificate settings, API endpoint errors, or expired credentials. To diagnose and resolve server misconfigurations:

  1. Review the server’s push notification configuration settings.
  2. Ensure that the necessary certificates and credentials are up to date and correctly configured.
  3. Test push notifications with various scenarios to ensure reliable delivery.

Troubleshooting Steps for Developers

In addition to user-side troubleshooting steps, developers may need to perform additional actions to identify and resolve push notification issues:

Examine Error Logs

Developers should analyze error logs to identify any errors or inconsistencies related to push notifications. Error logs can provide valuable insights into the root cause of the issue, allowing developers to address it effectively.

Debugging Tools

Utilizing debugging tools specific to the app’s development environment can help pinpoint push notification issues. These tools often provide detailed information about the push notification flow, helping developers identify where the problem lies.

Testing on Different Devices and Platforms

Testing the app on a variety of devices and operating systems ensures that push notifications function correctly across different environments. By conducting thorough testing, developers can identify any device or platform-specific issues and implement necessary fixes.

User-Side Troubleshooting

Users can also take specific actions to troubleshoot push notification issues on their end:

Check the App Settings

Users should verify the app-specific settings related to push notifications. In some cases, the app’s push notification settings may have been accidentally changed, leading to the issue. Users can follow these steps:

  1. Open the app’s settings within the app itself.
  2. Find the push notification settings and ensure they are enabled.

Clear Cache and Restart the App

Clearing the app’s cache and restarting it can often resolve push notification issues. This action refreshes the app’s settings and clears any temporary data that may be causing disruptions. Users can follow these steps to clear the cache and restart the app:

  1. Go to the device’s settings.
  2. Navigate to the app settings section.
  3. Find the app and select the option to clear its cache.
  4. Restart the app to apply the changes.

Reinstall the App

If all else fails, users may need to reinstall the app to troubleshoot persistent push notification issues. Reinstalling the app ensures that the latest version is installed, potentially resolving any underlying problems. Users can follow these steps to reinstall the app:

  1. Uninstall the app from the device.
  2. Visit the app store and download the latest version of the app.
  3. Open the app and verify that push notifications are enabled.


In this blog post, we have explored the common reasons behind push notification issues and provided troubleshooting steps to address them. Push notifications are crucial for app engagement and user experience, so it’s important to ensure their reliable delivery. If you encounter persistent push notification issues despite following the troubleshooting steps, we encourage you to reach out to the app’s support team for further assistance.

Remember, push notifications are a powerful tool for driving app adoption and engagement. By proactively addressing push notification issues, app developers can optimize the user experience and enhance the app’s effectiveness.
