Need the area code identifier back!

Since the last update all calls show up as "United States" whereas they used to show the City and State. I see two recent posts about this and neither has a valid or helpful answer. I have tried going to Settings> General and making sure my phone knows I am in the US region. It does. My Dial Assist is also ON (green). Neither of those items solve this problem. Moreover this problem is brand new, and came with the update.

Just to be clear, for example if a call came in from someone I don't have saved as a contact, and that someone was calling from the 615 area code it would say "Nashville, TN" and now it will say "United States".

This pertains to calls from strangers, this question is not related to saved contacts. I get tons of calls from random people every day due to my work and having the City/State display was very helpful. Can anyone help me get it back?
