Bulletin: Meta ads breakdown by channel update

Meta now requires per-ad-account opt-in for the impression_device breakdown, effective August 6, 2026. Because Meta's reporting API cannot return cost data broken down by both geo and channel in the same query, accounts without this opt-in will see incomplete data:

• Channel-level cost data may be missing from the default My Dashboards view
• Meta's data may be missing from Cost ETL

The same limitation also affects creative performance data broken down by channel.

Meta applies this opt-in automatically on AppsFlyer customer accounts. You do not need to take any action before August 6.

• If your cost data broken down by channel, or your creative performance data broken down by channel, is missing after August 6, the automatic opt-in has not yet applied to your account.

Take the following steps:

1. After August 6, check your cost data broken down by channel (My Dashboards) and your creative performance data broken down by channel.
2. If you notice a gap, contact Meta directly for guidance on enabling the opt-in, or reach out to your AppsFlyer representative for help.
3. Once the opt-in applies to your account, your data will catch up automatically through backfill shortly after.
4. You can also check directly in Ads Manager whether Impression Device is already enabled for the account. See Check Impression Device in Ads Manager below for the steps.
