Adding Comments
When working on an app item, the assignee or the manager at times might need to record comments on it.
To add comments, click on the app item for e.g your bug, risk, etc. On the panel of the item, click on More ▸ Comment. You can check the Notify Requestor checkbox if you wish to notify the requestor of the app item about this comment.
Once the comment is added, all the followers receive an email notification with the new comments.
