Yep I tried on my phone and no blue dot. The only thing remotely near me is my "Pin" and it's on the other side of the county down next to a river. LOLEarlier I was on my iPhone when I clicked that first link Dirk posted. I have given GPS access to Google Maps and Apple Maps in the OS.
On the computer, I have disable Location Services for all except for the Find My Mac service.
Have you tried from your phone?
Now I am curious.
