Microsoft recently updated Microsoft 365 usage analytics on September 1, 2021, to pseudonymize user-level information by default. See Privacy changes to Microsoft 365 Usage Analytics for more information. This change affects tyGraph Pulse, tyGraph for SharePoint, tyGraph for OneDrive and tyGraph for Yammer.
A complete tyGraph data harvest cycle is required to fix the reports.
Global administrators can revert this change in the Microsoft 365 admin center by going to:
- Org Settings
- De-select In all reports, display de-identified names for users, groups, and sites
- Click Save
