The Platform filter has been removed from all Demographics metrics in the Facebook Ads integration, as well as in the Instagram Ads integration. This update was made necessary by a native Meta update that caused incompatibility issues.
The change affects all metrics and related widgets under the Demographics section in custom Dashboards and Reports.
FB-Ads-Demographics-Metrics
Affected Metrics:
Metrics using demographic dimensions (age, gender, city, country) can no longer use the Platform filter.
Unaffected Metrics:
The Platform filter remains available and functional for metrics in the Campaigns, Ad Sets, and Ads sections.
If you have widgets configured to use the Platform filter with demographic dimensions, you'll need to revisit and adjust these widgets.
