I know it can be frustrating,

This [answer](https://discuss.elastic.co/t/geoip-filter-does-not-work-with-a-subfield/306750/2) might help, but it doesn’t go into details, so you will have to work on it.

Providing a single reproducible example will allow me, Leandro, Rios, David, or others to provide much more customised advice.

Please show us the problem, not just the error message.
