+++++1 Just signed up for a trial for personal use, with a view to using in our startup.
Lack of notifications on items when the due date/time rolls around is a critical gap. Using Zaps and the like is just a bandaid and not a sufficient solution.
Until that is in place, it just won’t do what we need, despite it’s benefits in other ways over Trello, Asana etc
Sorry - but this is a major gap.
