DVM Certificate Inventory Shows No Data Despite Healthy Endpoints in Defender for Endpoint

Hi Team,

I'm testing Microsoft Defender Vulnerability Management.

Current status:

- Defender Vulnerability Management Add-on enabled

- Certificates inventory tab is visible

- Software Inventory populated

- Security Recommendations populated

- Windows and Linux devices onboarded

- Linux mdatp health = healthy:true, licensed:true, cloud_enabled:true

- Devices have local certificates installed

- Certificate Inventory page shows "No data"

The DVM Add-on was enabled more than 36 hours ago.

Has anyone experienced a delay in Certificate Inventory population or are there additional prerequisites beyond DVM licensing and device onboarding?

Thanks.
