You are reviewing whether a named B2B Meta campaign should retain, exclude, or evaluate Audience Network. Use only the evidence supplied below. Meta help reviewed 2026-10-31 says Audience Network can reach partner mobile apps; Awareness and Engagement support video only, while Traffic, App promotion, Leads, and Sales are also listed. Format and placement eligibility vary. Meta is gradually removing ad-set manual placement selection for Leads, App promotion, and Sales; Awareness, Traffic, and Engagement retain it. Account placement controls for auction campaigns can affect existing and new campaigns, may take up to 48 hours for existing campaigns, and do not apply to ads about social issues/elections/politics or financial products/services, employment, or housing. Controls and reports may roll out gradually. Publisher block lists can cover identified Audience Network apps; content block lists in the cited Meta overview do not list Audience Network. Meta inventory filters use Expanded (default), Moderate, and Limited levels, exclude apps on Audience Network, and are distinct from publisher block lists. Publisher delivery reports show approximate impression information for named Audience Network placements, delayed about 3-5 days; they do not supply CRM placement joins. Verify current help and live account before recommending an actual change.

Task: Read the input below. Produce one review record for each distinct account/campaign decision. Use the exact 18 numbered field names in the exact order shown below for every record. Keep values concise but complete. Cite the supplied evidence name, location, date, and scope for consequential claims. Separate what Meta documents from what the supplied account evidence actually shows. Never invent account observations, controls, approvals, results, or receipts. If input is blank, a placeholder, the wrong kind of material, contradictory, or missing a required fact, mark the affected value Unknown and name the exact evidence to obtain under fields 15 and 18. Preserve measured zero only when a complete source establishes zero. Do not divide spend by campaign-wide qualified leads to calculate a placement-specific cost. Require placement-linked, deduplicated, mature qualified outcomes and a defined qualification rule before qualified-cost comparisons. State denominator and arithmetic. Divide only by a positive qualified count. Positive spend with a verified zero qualified count has no finite cost per qualified outcome: report the spend and zero outcomes, not $0 and not missing-data Unknown. Zero spend divided by zero outcomes is undefined. Preserve the observed zero counts. Do not call observational placement results causal. Identify every campaign affected before recommending an account control. For special-category campaigns, do not assume account controls apply. A recommendation is not authorization; do not claim a setting changed. End with a one-sentence next action after each record. If multiple campaigns are supplied, keep records separate; never blend their metrics.
