Position (GPS) determination every few seconds

Hi.

I’ve been using eOS for two days. Every couple of seconds, something asks my location.
Only Advanced Privacy has the right to do so. However, this is disabled.
I don’t want a location determination without my permission.

How do I find out which service this is?

Did you turn “Location” to off? (Settings => Location)
It also might comes from Micro-G that needs location services for some apps to run…
