First, thank you for the developers of graphene OS. I'm enjoying very much the OS and the safety/privacy feeling it provides!
I have an issue with the application wise. The app managed to access my current location's country and I don't get how.
The app is installed in a separate user profile, no google services. Only additional apps to the defaults apps are Aurora and proton VPN, using the graphene VPN always on kill switch and starting up with a specific country's profile in the UK. No location permission given to wise, only network, sensors and notifications.
Yet, the other day while being in Sri Lanka (traveling there), the app sent me a message "welcome in sri Lanka" (I took a screenshot but I think I can't upload it here through the forum for mobile). At that time, I had a sri Lankan sim card but I doubt it found out through this (if it even could) as I did not have that message in the past based on the sim' origin country.
Any idea how that app got access to my location ? Could it be some "weakness of the OS" or there is something I am missing ?
When i was using a standard android phone with google, wise was always able to follow me everywhere. No matter my IP address (using proton vpn all the time).
