On May 15, 2024, Google's FCM service will start to expire stale push tokens for devices that have been inactive for more than 270 days. You may see a spike in Android unsubscribes when sending notifications due to this change. Don't panic! These are devices that have not been online in over 270 days and are part of Google's Best practices for FCM registration token management. If the device does come back online and opens your app, OneSignal will automatically resubscribe them to push if they were previously subscribed already.

More details in our FCM Expired Token FAQ.

Android's Live Notifications deliver live, dynamic content in notifications to enhance user engagement and app interactivity. This is a feature similar to iOS's Live Activities feature (introduced with iOS 16), but uses its own set of tools and APIs that enable similar functionalities.
