I have setup Membership plugin.
I set a “Visitor” access level.
I created a “Staff” access level and a “Staff” subscription which are both connected.
On the “Visitor” access level, I have a Negative Rule with all menu items under “Member” checked.
On the “Staff” access level, I have Positive Rule with all the menu items under “Member” checked.
When I am logged in with a “Staff” member, I see no difference or change. IE, all the menu items under “Member” are not shown.
