Hi, @RASHMAAR-2635
Thank you for posting in Microsoft Q&A forum.

Hi @AllenLiu-MSFT
This option is not activated:
Use PKI client certificate (client authentication capability) when available
Do the clients and MP have a good communication now? Do the clients get all the policy from MP? Can the clients get the application and software updates deployment? In other words, does this warning have any impact on the clients.
We may check LocationServices.log and CcmMessaging.log on the CMG clients for more details.
