Due to a technical issue, the processing of custom audiences has been disrupted since 10:00 PM UTC on October 7, 2024, and is expected to return to normal by 10:00 AM UTC on October 8, 2024. During this period, new audience processing has failed and experienced delays for existing audiences where changes were made. Campaigns associated with failed audiences may encounter bidding issues, while others will continue running using audience data processed before the issue occurred.
