Usage report not showing a users usage

Hi paveley1985 ,

Report Page Views rely on client telemetry and can be affected by undercounting and overcounting of activities due to inconsistent network connections, ad blockers, or other client-side issues. Report View metrics relies on activity data collected from Power BI service, and matches the aggregate counts of activities in audit logs and activity logs.

Additionally, you can go through this Worked example of View and Viewer metrics which explains how a report view count is calculated.
