With the API there are 2 metrics under page engagement, checkins by country and checkins by locale. Is it possible for you guys to add in the equivalent of checkins by city? It exists in the insights page but doesn't seem pull-able via omni atm - is that because it doesn't exist in the API?
All of these should be implemented inside the Omniscope Facebook connector. If there are any missing please let us know. Unfortunately I can't see any "checkins by city" or equivalent.
