I’m using a Google Nexus 4 phone. I go to “tap to edit your home location on the map” and the map appears with a red circle about 8 blocks in diameter. I’m in a densely populated area, so I’d like to reduce the size of my geofence. When I click on the black dot at the bottom of the circle, I get a message that says, “Geofence Drag handle to resize geofence.” Is there some secret to dragging it? Because touching and holding the black dot and then sliding my finger simple zooms in on the map or zooms out – but the geofence remains the same size. Is there an alternate way to do this via computer desktop?
