Google+ for Work known issues
Age Correction
Restricted communities
Google+ Hangouts video calls
After correcting a user's age to above or below 13, there is sometimes a delay before the new state of the user's Google+ profile is reflected on the Admin console.
Restricted communities might not yet be searchable in your domain, even if the creator of the restricted community chose to make it searchable.
Because users can't restrict Google+ events to your organization, Google+ Hangouts video calls they add to events are always unrestricted.
