Some changes are rolling out to certain Android users of Google Maps running v9.32. Unfortunately, not everyone is receiving them at the same time. You will know if you are one of the lucky ones if you have the Wi-Fi Only option listed in Settings. Toggle the switch on and the mapping features are no longer connected to a cellular network. The idea is that users can save data by using the app to navigate in certain areas while offline.
If you have Wi-Fi Only enabled, you will see a blue bar across the top of the screen indicating that the feature is “on.”
