Error getting Device Data

Have an issue with Device data not displaying in the Defender XDR portal.

On the Assets/Devices menu I can search and find a device, but when I click in it to see the properties- the page displays only 50% of the time. Mostly it stays loading for about 30 secs then displays the error "Error getting Device Data"

Occurs regardless of what permissions are applied, occurs regardless of the browser or incognito modes, regardless of who is logged in.

Done basic troubleshooting from MS and even MS support cannot find the answer so far.

Has anyone seen this before?

Cheers
