Hi Aleksander,

Is there any way to disable XTRA location assistance? From where modemmanager receives assistance servers information? Is this comes from the modem? I see requests to download these files on cellular link. Who starts the download? Is it modemmanager or modem?

In some private APNs, location assistance servers are not reachable or not needed. Is there a way to disable location assistance?
