JMWE's new Transitions tab option gives users a precise view of transitions and if you are using this app, it is enabled by default. However, some older Jira Cloud instances might show a second "old view" Transitions tab. This is a legacy tab originally provided by Jira Suite Utilities (JSU).
To avoid confusing your users with two similar options, you might want to disable one of the tabs. But which one should you keep?
