Hello,
I'm using GrapheneOS on my pixel 8a since a few days and I noticed a specific app for a service provider in Italy (package id: uk.co.novaware.telepass.android ) works only partially unless the "Network Location" and "Geocoder" settings are set to "Apple server" and "Nominatim server" respectively. If these settings are left with "GrapheneOS proxy" the app will start but one of the core functionalities (unlock local services when they are close) fails with a generic error.
I couldn't find other apps needing this specific workaround hence I created a new topic both to let other affected users know about it and to let developers' know that I'm willing to share logs and try to identify the underlying issue if there is an interest in fixing this.
Thanks for all the work on GrapheneOS!
