Purism sent me a tool gnss_test.py which gets a fix after ~120 secs as:

The values matches closely to what my UbuntuPhone E4.5 detects (in the pic the values in front of the decimal point are blanked-out):
I’m still struggling with a app Maps because even if the phone has a fix, the location shown in the map seems to be based on Wifi or cell towers.
