Android can get notification synchronisation between all devices
Google is working on a new feature that will allow you to synchronise notifications between Android devices. This will be possible thanks to the "Sync across devices" feature, which is currently being tested in the Android 15 QPR1 Beta 2 beta.
Here's What We Know
This new feature will allow users to receive notifications on all their Android devices that are connected to the same account.
If you open or reject a notification on one device, it will automatically disappear from other devices.
This feature may be available not only for Pixel devices, but for all Android devices.
However, since the feature is still in testing, it is not known whether it will make it to the final version of Android 15. There is a possibility that Google will leave it exclusively for Pixel devices or decide not to include it in the release.
