Campaign-level broad match and automatically created assets auto-migrated to AI Max from September 1, 2026

Search campaigns using campaign-level broad match or standalone automatically created assets are upgraded in place to AI Max during September 2026 (trackable via campaign.aca_migration_date_time and broad_match_migration_date_time); creating new legacy configurations was blocked on August 3, 2026, and API versions released after September 1, 2026 remove the legacy entities entirely.

Default migrated settings: campaign-level broad match -> text customization OFF, final URL expansion OFF, search term matching ON, brand lists preserved; standalone ACA -> text customization ON, final URL expansion OFF, search term matching ON. Older active API versions keep supporting legacy settings until their scheduled sunsets (around September 2027).
