How to fix the "Unregistered" push test error?

In some cases, Batch will fail sending a send test to your device. This happens when the token you are targeting is not valid anymore.

In some cases, the dashboard may show an error when you try sending a test notification to your iOS or Android device, or to your web browser: "Push test has failed NotRegistered".

This usually happens because the device token is not valid anymore. Each time you reinstall your app, Apple or Google resets your existing token and generates a new one for your device, invalidating the existing one.

To fix the issue, you need to find the Installation ID attached to your new push token: iOS / Android / Web.
