We are trying to get notifications if there is no activity across the entire board. There will be several tasks that will be inactive for a long time, so by task doesn’t work for us. We are really only trying to get notified if there is no activity across the board for 2 weeks.
Welcome to the community! There is no such thing as a board activity timer. What you can do (with platforms like Make or build an app) is to listen to column change events and reset an external timer when there is a change. If the timer reaches xxx days you can notify. Key here is to store that timer somewhere outside monday.
