Can not leave a joined federated group
I don't know, how it should work per design... But my user-experience is not, what i expected...
I can join a group on Instance B from my account @user@instance.A, if joining is allowed on Instance B.
On my instance A i can NOT see other members of this group@instance.B If i try to leave group@instance.B i'm not allowed to with message "you can not leave group, because you're the only admin in this group".
Show members in this group on instance.A in Administration-Panel shows me only as "Member" not as "Admin".
It seems, the groups are not synced correct or federation of groups is broken.
