   We are continuing to work on a fix for this incident..

2. resolved

   **Summary:** Meta deprecated the `breakdowns=dma` (Nielsen DMA) parameter across all Facebook Marketing API versions effective June 22, 2026\. This caused failures in the `ads_insights_dma` and `ads_insights_demographics_dma_region` streams for the Facebook Marketing source connector. **Resolution:** The connector has been upgraded to v6.0.0, replacing the deprecated DMA streams with Meta’s recommended Comscore Market equivalents. This is a breaking change. **Affected streams:** * `ads_insights_dma`→ replaced by`ads_insights_comscore_market` * `ads_insights_demographics_dma_region`→ replaced by`ads_insights_demographics_comscore_market_region` **Customer action required to resolve:** 1. Upgrade the Facebook Marketing source connector to v6.0.0 2. Refresh the source schema to discover the new streams 3. Enable the new Comscore Market streams and reset them to backfill data 4. If using Custom Insights with the`dma`breakdown: update the configuration to use`comscore_market` instead.
