Meta is making several Facebook Ads reporting breakdowns opt-in per ad account; reports that rely on them may return empty until the breakdown is enabled in Meta Ads Manager.

This is a Meta-side, per-account setting change — not an Improvado extraction issue. It's resolved by enabling the breakdown in Meta Ads Manager; once enabled, Improvado collects the data automatically.

What's changing

Announced in Meta's May 2026 out-of-cycle API changes and effective August 6, 2026, several reporting breakdowns become opt-in per ad account. If an account is not opted in, report types that rely on these breakdowns may return empty for that account:

• Device / placement (impression_device) — and any report that combines it, e.g. placement/device reports.
• Frequency (frequency_value).
• Hourly, by audience time zone (hourly_stats_aggregated_by_audience_time_zone).

How to fix it

In Meta Ads Manager → Breakdown, enable the relevant breakdown for each ad account. This must be done per ad account and requires account-admin access on your side.

Good to know

• Data starts flowing from roughly the next day and appears to be forward-only — historical periods before you opt in are unlikely to backfill.
• For these particular breakdowns, Improvado can also retrieve the data through Meta's asynchronous reporting as a fallback, so the impact may be reduced — but enabling it in Ads Manager remains the reliable fix.
• Once enabled, Improvado picks the data up automatically — nothing changes on the Improvado side.
