Group Members still can be viewed even if it's not shared with everyone!.
When a new group created and shared publicly I don't want non-group members to view whos in that group, so when I came by the question "Who can see the list of members on the Members tab" I chose All group members expecting that only the members will see whos inside that group
unfortunately, everyone is able to see the members (users not a part of my organization or any other organization)!
Then I tried to create a new group and this time I chose Only group owner and managers, the result was the same! members are exposed to everyone!
here is the group link
