Starting on May 1, 2025 , we will begin to automatically enable brand guidelines for Performance Max campaigns that use the same brand assets (BUSINESS_NAME, LOGO, and LANDSCAPE_LOGO) across all asset groups.
  For Google Ads UI users : The process will begin on May 1, 2025  for customer IDs that exclusively manage their campaigns using the UI.For API users : This process will begin on June 1, 2025 . 
The overall process across all campaigns is expected to be complete by July 31, 2025 .Important Notes: 
  Only campaigns using consistent business names and logo assets across all asset groups will be automatically migrated. Campaigns with variations in these assets will not be migrated. 
  All eligible Performance Max campaigns under a customer ID will be migrated simultaneously. 
  After migration, each migrated campaign will have its own set of brand assets stored at the campaign level using CampaignAsset 
  You can tell if a campaign has been migrated by checking its Campaign.brand_guidelines_enabled 
 
Actions Required Campaign.brand_guidelines_enabled field. This will tell you whether to include brand assets in the new asset group.Campaign.brand_guidelines_enabled field.
