The Instagram connector for Google Data Studio pulls in post location data with name (text string) but doesn't pull latitude and longitude from the public location endpoint.
Since location names are mixed between cities and specific places, that table can't be used for geomapping, so we need the connector to also pull in latitude and longitude to be able to create geo map reports.
thanks for reporting this!
Our developers are on it, and an update will be released later this week.
the location data is now added to the Instagram connector. Please Refresh Fields in the connector settings, to make sure you get the latest setup.
If Geomaps do not instantly work for you, please add a Filter with setting Exclude Location ID Less than (<) 0. See attached image.
Thanks. Works flawlessly.
