MetropleX thanks for the quick reply. I'm using Vanadium and sandboxed Google Play Services. I have allowed Vanadium location permission and allowed location permission to Google Mapa Go but not allowed that permission to Google Play Services.
When I open the Google Maps Go (the little Google Maps app) it redirects to Vanadium browser and "my location" icon at bottom right has a cross line. If I change location permission in Vanadium app info from "allow while in use" to "ask allways" the browser request for the permission when I click "my location" icon but the cross line do not dissapears and my location is not displayed.
If I open "maps.google.com" directly at Vanadium the "my location icon" does has also the cross bar, when I click on it Vanadium request for the location permission and, if I allow it, my location is displayed and the "my location" icon becomes blue (after a while).
I have also tried to set Chrome browser as the default browser and it works exactly same as Vanadium.
I think maybe is a issue in the comms over the browser (Vanadium or Chrome) and the app.
Finally, I have tried same (with Chrome and also with Vanadium) in other phone running other OS than GrapheneOS and, when I allow location permission to the browser and to the Google Maps Go it works fine.
Thanks again
