[deleted] even if using sandboxed Play Services, if you don't disable the OS reroute toggle to the OS Location API (GNSS/GPS) it will always use GPS. When using GPS it can take a little longer to gain a lock. I you wish to improve the speed/capability (indoors) then you must disable the toggle and enable wifi/bluetooth scanning to use Googles network based location service.
If when using Go/PWA or Vanadium you get the green dot location indicator you should just need to wait for a lock.
Or it could be an issue where a lock is a prerequisite and therefore using GPSTest prior to launching Go/PWA or maps.google.com in Vanadium might resolve it.
[UPDATE 1] Just tested Vanadium and maps.google.com
with no Play Services it got the lock as you say just going to try Google Maps Go now...
[UPDATE 2] Yes Google Maps Go is indeed more of a chore, not got it to work yet and doesn't seem to recognise the default Vanadium permission.
