Hi Le, Angela,
Thank you for using our Microsoft Advertising Learn Q&A Platform!
We understand that your Xandr DMP audiences historically received Data Usage Reports to track usage and spend, and that these reports stopped being received around February 2026. We appreciate you sharing the report configuration and context.
For investigation of missing report deliveries and questions regarding the availability of backfilling historical reports, we recommend contacting the Xandr Support team directly through their support portal.
To reach the right support for your concern, you may go to this link Microsoft Advertising Customer Support Portal and Sign in to the Microsoft Advertising Customer Support Portal using your Microsoft email address then click “Contact Support”.
Thank you for your understanding, and we wish you success in resolving this matter.
