Why doesn't the States panel in the report show purchases, leads, or conversions?
This is a Meta limitation: Meta does not report conversions by state. That's why the States with the most delivery panel only shows delivery metrics (spend, impressions, reach, clicks, CTR, CPC, and CPM), and not purchases, leads, conversations, or ROAS.
To see conversions by audience, use the Age, Gender, Placements, or Best days and times panels, which include those numbers.
