I'm trying to enable the Sunset to Sunrise option for Nightshift. When I do so, a pop-up informs me that it "requires location for time zone to be enabled," and offers a button to send me to the appropriate privacy settings page. Here's a screenshot of the pop-up.

But the privacy settings appears to have no option corresponding to what's referenced in the pop-up. Here's two screenshots showing my privacy settings:

As far as I can tell, all privacy settings are enabled, but Night Shift still refuses to enable sunset to sunrise. Does anyone know how I can enable it?
