iPhone users can now view enriched Google Fit data collected from your smartwatch (steps, distance, calories and HR if applicable) and edit your notifications and calendar settings from within the app.
Responding to Gmail from your smartwatch is no longer supported.
Assistant will fully function on the watch without the Google Assistant app being installed on your phone. To configure additional Assistant settings, such as Home and Work location setup, users will need to download the Google Assistant app.
Users will no longer have the smartwatch face picker in the companion app; all smartwatch face settings can be done on smartwatch. Watch face picker in the Wear OS by Google app will be replaced with an improved watch face management experience coming soon.
