I am trying to show an additional tab on one of my lists, only to a select group of people, and I have set the field “Which groups can view this tab?” to the correct grouping that I would like, and it is not working at all. If I leave the “Which groups…” field blank, then I can correctly see the additional tab (but so can everyone at this point). When I set the field to equal the specific group, it disappears (and I have verified that I am in the group). I am not sure what is causing this, as I have used this functionality before in other lists and they have worked as expected.
Any help would be appreciated.
