I was doing really well. I set up an unsubscribe email, I assign it to the correct lists, and I put one user in that list. I sent out an email to that user. I received the email. I click on the unsubscribe link, and I'm shown the Unsubscribe page.
This is all looking great. So I click on "Change my preferences". I ensure that the list is selected. I click "Update my preferences." I'm sent back to the home page. I see "Subscription successfully updated" in the message panel.
However, having done this, if I look at the subscriber in question in AcyMailing > Subscribers , their subscription to the list in question is still active. What am I doing wrong?
