Mine is working fine. When I checked it after the update I was just asked to re-enable it. Maybe check to make sure that Location is turned on as a permission for "Phone". You can do this by navigating to the app info for Phone and going to permissions and toggling it on. Hope that helps!
Thankyou, I just tried that that and no change. I've gone through my settings and changed permissions with no change. I know it was working before the pie update but not now. Not the end of the world but it is pretty handy to have.
