My team and I currently have an email-to-board integration set up between a dedicated support email and our trello board. Everything sent to that email address shows up in our "incoming" column on the trello board.
The issue we're having now is that whenever one of these emails are replied to, or gets replies (even from the original sender of the email), it doesn't update the existing card, but instead creates a new one.
According to https://support.atlassian.com/trello/docs/creating-cards-by-email/ it should update the existing card with comments instead of creating an entirely new card, but this no longer seems to be working for us - it did for a time, and then stopped working. We've been just dealing with it by deleting the extra cards, but the volume of emails we're getting has increased to the point where it's becoming difficult to manage.
Does anyone know if the "add replies as comments" feature is gone now, or what I can do to get it back?
