Before upgrading to JIRA 7.1.10, we would be notified if another user made changes to an issue we had open in our browser. For example, if I was creating a comment in an issue, and another user added a comment in that same issue, I would see a notification in my browser to tell me of the new comment.
Since we upgraded to JIRA 7, this no longer happens.
How can I restore this useful behaviour?
