Often we have people who use Workfront to post about progress or roadblocks for a task. They do not @mention the project owner, though. That means we miss out on a status update, and have had to add in a manual step every week for the PMO to spend time reviewing the "Updates" tab in all of our projects to see where we have potentially missed receiving an update.
The Project Owner should automatically be notified with the comment posted on one of their project tasks or issues. This would also be helpful when a user enters a comment on the Project > Updates page.
