User impact: Admins’ Microsoft 365 admin center dashboard page may not have loaded any content.

More info: Some admins may have seen a loading error indicating that “the app tried to reference a color that didn’t exist.”

We reverted this update and confirmed through our service telemetry that the issue was no longer occurring.

Scope of impact: Any admin accessing the Microsoft 365 admin center during the impact time period may have been unable to load content on their dashboard page.
