As documented at 2.0 - Delegation for all!, the editing of Issue Types, Permissions and Notifications is being moved into the Self Service path. This means that in a future release the 2.3 release of Delegated Project Admin Pro for Jira - editing of Issue Types, Permissions and Notifications in Guided Path mode will be removed. It is currently only available for customers that had the 1.x series of the app installed.
