Facebook → Google Analytics / Google BigQuery pipelines have become generally unable to export cost data and refresh the access.
Our engineering team is currently working on investigating the issue. We will provide an update on the situation tomorrow, November 3, at 16:00 UTC.
All cost data for the period of the pipeline outage will be imported to your Google Analytics property / Google BigQuery project as soon as the pipeline will be back to work.
UPDATE: 3/Nov/2021 15:55 AM (UTC):
The issue has been already resolved.
The cost data is loaded in Google Analytics / Google BigQuery.
