Google investigating Ad Manager Reach report error

Google is currently investigating an issue that is causing incomplete data in Ad Manager Reach reports. This issue affects reports with dynamic date ranges, such as 'Last week (Sun – Sat)' or 'Last 93 days', as well as fixed date ranges with start or end dates beyond March 20, 2024. The incomplete data pertains to the reach reporting data for any Orders or Line items that are still actively delivering beyond that date.

As a temporary solution, Google has suggested using the 'Estimated Total Unique Visitors' Reach report metric. This metric is not affected by the issue and provides an estimate of unique visitors to report an estimated reach for as many rows as possible.

Google has announced that it will provide an update on the situation at 5pm ET on April 1. This update is expected to give more information about the problem and possibly a timeline for when it will be resolved.
