AD groups in update management (azure automation accounts)

Even though there weren't any answers:

Things are working now. A few days later, i was able to see the groups supposed to be. 🙂

What should to be fixed is the fact, that the feature "usage of groups" is not ideally implemented. After choosing a group, saving and reopen the config you can see, that the single machines were listet, no longer the group name, which results in the fact, that newly addede machines to a group woun't appear here.
