PENDING SCCM with Windows 11, version 24H2 x64 2024-12B - all unknown devices

[jrt]

Hi all. I have been pushing out 24H2 2024-11B. The other day a new version appeared, 12B (

What's happening now is that everything is showing as Unknown. I have downloaded the update, added deployments and left it overnight, but same thing. Any ideas??

I don't think I can continue with the older version, so I have removed all the deployments by disabling them.

My SCCM is version 2309.

Thanks.

Noticed my other updates are doing the same thing, for Office 365 and general Windows 10 and 11.

What i am guessing is that the update is not evaluated properly. We are also deploying the same update next week and I will see if i can resolve it.
