According to the user guide, if I select contacts by search and then start a CiviMail mailing to them I should be offered the "Unsubscribe group" option, as shown in this helpful screenshot posted on another question.
I can't get this to appear for the life of me. I'm on 4.7.27 under Wordpress. All I get is "Hidden Group 1234" in the Recipients field. Has this behaviour changed?
The reason for the question is that I want to do various searches to segment people but maintain a single unsubscribe group that would apply to any of my searches.
EDIT This might be a "please help me fix my CiviCRM install" question instead of a "how's it supposed to work" question.
On at least two of my installs (one Wordpress, one Drupal7) I don't see the Unsubscribe group option. Huh?
Reproduce: Search all contacts » Select some contacts » Mail by CiviMail.
Expect to see Unsubscribe Group option, but do not.
I agree with @petednz that this works on the 4.7/Drupal7 (actually 5.0.0 at time fo writing) demo site.
