The problem: With auto-apply on, placement exclusion checks exclude anything that meets the criteria. But most accounts have a few placements you'd never exclude regardless of performance: partner sites, brand-safe publishers, your own properties. Right now the only way to protect them is to leave auto-apply off.
What we're building: A new account-level custom attribute, Whitelisted placements, where you list the placements that should always be left alone. Placement exclusion checks skip them, so you can keep auto-apply on.
Who this helps: Anyone running auto-apply on placement exclusions.
