Meta Ads Reporting Breakdowns Opt-In: August 2026
Since 6 August, a Meta report full of zeroes can mean your ads died, or that you did not opt in. Meta reports both as success.
Meta now requires per-account opt-in for three Ads Insights breakdowns: device, hourly, and frequency. The change took effect on 6 August 2026, announced in a Marketing API changelog entry dated 8 May 2026. Accounts that have not opted in receive an empty data array with a success response. No error, no warning, just a dashboard rendering zeroes.
The device restriction catches any breakdown combination that includes it, so a routine device-by-placement query is affected too. The exposure is largest where owner-operators actually look: third-party dashboards. AppsFlyer and connector vendors have published bulletins because reporting tools and attribution platforms pulling these breakdowns now show empty charts that are indistinguishable from a performance collapse.
Why is your Meta Ads dashboard showing zeroes since 6 August? Possibly this setting. Pull a device or hourly report covering 6 August onward; if it is empty where 5 August had data, an account administrator can enable the breakdowns under Additional Breakdowns in Ads Manager, and reporting tools can enable accounts programmatically through the new feature-settings endpoint. Vendor bulletins report that historical data returns after enablement.
Our math: The cost is not the setting, it is the reaction to it. Modelled: a store spending $3,000 CAD a month on Meta at $50 per purchase books 60 purchases a month, two a day. An owner who reads an all-zero dashboard as a collapse and pauses for three days while investigating forfeits about six purchases, roughly $900 at a $150 average order, and restarts ad sets that then risk re-entering the learning phase. The zeroes cost nothing. Believing them does.
Our read: An empty success response is the most dangerous kind of default: the platform's answer to "how are my ads doing" became "fine" and "nothing" at the same time. Our recurring position is that platform-reported numbers require attribution to the platform reporting them. That includes zero. Before you diagnose the account, verify the setting.
If your Meta reporting flows through a dashboard and nobody has checked the device or hourly view since 6 August, that is this week's audit.
