Azure Active Directory , Sync Azure Devops

we have groups in Active directory, some of them do appear in azure devops, some do not.

The groups exist for two months, so it’s not a matter of automatic sync or log off log on, I tried everything and some of them still don’t appear and even when I created new ones they don’t appear either. I think the sync stopped at some point between the active directory and azure devops.

How can I verify this and arrange that all the groups in active directory will appear in azure devops.

I repeat, they all have the same settings, there is nothing special and that is what is strange here…
