Hi,
It seems there has been a reversion here? Since starting with Discourse, as admin, I’ve had access to all groups. In the past couple of weeks, I have been unable to view many of them.
This is difficult because the group owners will ask me to do bulk invites through the admin interface to invite new groups of members to their group (and the associated private Categories).
In light of this, I would strongly advocate for all groups being visible to admins.
