In the past, the issue view in Jira Cloud has displayed a transition tab, the feature some have come to rely on for activity information essential to their business processes. For example, managers and auditors could have a clear understanding of what actions have been taken on issues, that the right people work on or approve them, and that the processes always follow the appropriate workflow.
Since then, on the new issue view this tab is no longer available and only older Jira Cloud instances still show this option. However...
Jira Misc Workflow Extensions (JMWE) for Jira Cloud now includes the Transitions history tab in the Activity section on the Issue View screen. It lets you easily see all issue status transitions, when and by whom they were triggered, all in one list. You can also see Time in status for each transition so that users can easily evaluate status changes of an issue.
It can be found by navigating to the issue details screen in the section called "Transitions".
The JMWE Transitions tab is enabled by default, but you can also turn it off to remove it from user views. If you choose to hide the JMWE's Transition tab, uncheck the option on the configuration page of the JMWE app.
