my ad reports shows the country as "not shown".. what is this ? I have filtered ad views for USA, UK, AUS, and CA are these ads shown for other countries somehow ? I mean like proxy users ?
Internally the system is logging/tracking country for every click and impression, but I haven't yet decided on how to expose the info, so the column is a bit of a placeholder (no one sees anything other than "not shown" right now) until that decision is made.
