+                    <p>Location sharing in Google Maps is implemented in Google Play services. It
+                    requires enabling both the Location permission with "Allow all the time" and the
+                    Physical activity permission for Google Play services. Our location rerouting
+                    feature reimplementing the Google Play location service using the OS location
+                    service does not apply to Google Play services itself, so Google Play services
+                    won't use the OS network location service. You can use the instructions above
+                    for enabling network location via Google Play if you want this. You could
+                    continue using rerouting for other apps or disable it to avoid needing 2
+                    separate network location services enabled.</p>
