Soon after Google rolled out its new Google Maps system update for the Wear OS 3, several users across the world are reporting a bug related to the addresses.
According to the issue reported by the Pixel Watch and Galaxy Watch owners on Reddit, the Google Maps app on their devices is asking to set home and work addresses. For your information, this address is already mentioned on the device.
Same as your device, Google Maps on the Wear OS app pulls this home and work address data for a quick shortcut to start navigation. If you also facing the same issue then one user suggests that you must uninstall updates related to the Maps through the Play Store. Meanwhile, the issue will be fixed in future updates to Google Maps for Wear OS.
