I entered promotions after: 2016/01/15 before: 2017/09/01 in the selection box and clicked the select icon. Gmail shows no messages. But if I display mails from the promotion tab with no selection, it shows mails from today (Sep 17) to August (and before). This is part of my 'clean mails' procedure, and it used to work about three months ago. This seems like a bug to me.
Am I doing anything wrong, or has something changed?
