It's quite confusing that a Scope of a Cost Tracker does not update automatically.
It is based on a Jira Filter which, by nature, updates automatically all the time. But Cost Tracker has a confusing wrinkle: It doesn't actually update to the filter unless you click "update scope" (in the notification or in the scope dropdown).
It would be far more helpful, logical, and easy to use if the Scope updated automatically by default. (Perhaps each Cost Tracker could then have an option to NOT update Scope automatically for those that need that.)
