The current Google Pixel Watch is built on Wear OS and includes the latest updates to the platform, Wear OS 3.5 based on Android 11.
Unfortunately, Pandora does not support Wear OS and the app is no longer available for download in the Google Play Store.
The feature request Standalone for WearOS devices is the best place for feedback and to vote for product ideas you'd like to see for the Pandora app.
If you've previously downloaded the app to your watch, you'll continue to have access but we can't predict the behavior you’ll experience. You may find that it does not function as well as other devices.
