How to use "regions" as Firebase Remote Config condition?

Question

When defining a new condition for Firebase Remote Config, I can see that there's the condition of "Country/Region". However, after tapping on the "Select countries/regions" only countries are available in the list - unlike in Audiences where regions like "Texas" are selectable. Does anyone know how to use the region as an RC condition?

Answer 1

According to the official documentation regarding condition rule types , at "Country/Region" it is said:

Select one or more regions or countries.

This rule evaluates to true for a given app instance if the instance is in any of the regions or countries listed.

So it's a country or a region and not a country and a region. So you cannot select a region within a particular country. And it makes sense since when you create a rule, the device country code is determined using the device's IP address in the request or the country code determined by Firebase Analytics (if Analytics data is shared with Firebase).
