Field-tested by my team. ROAS improved roughly 30% versus the lookalike audience we ran before. Bought it for a India-focused charter school lohit, arunachal pradesh, territory cut. Couple of small gaps but workable.
Thanks for the honest feedback, the points you raised are on the refresh checklist for the next pull. If you want the gaps fixed sooner than the next refresh, open a support ticket and we'll spin a one-off pull.
