A common limitation with Jira is task/issue sharing with multiple users or teams, especially those who have no access to the particular Jira project, or those who are not in the project team. For instance, the client needs to be alerted about a bug during the software development process, but as an external user, he or she can't view the issue and leave comments. In such cases, development teams could only create the screenshots of the issue in Jira and send them to the client's external mail server.
On the other hand, there could be multiple project teams handling some aspects of the same task, and emailing about such issues from Jira directly poses a challenge. Thus, although Jira works exceptionally well for tracking the progress of a single project and in its environment, such situations, as described above, often result in limitations to a section of users.
