I understand epiclink nor parentepic don't work on Nextgen.
So I use parent = "EPIC-1234".
But "parent" does't show subtasks in an epic.
Is there way to show subtask in an epic with JQL on Nextge.
Hello @Naoki Yonemitsu
I don't believe there is a built-in method in Jira for getting both the child issues of an Epic and the sub-tasks of those child issues for a team managed project. You might be able to find a third party app that provides that functionality, in the Atlassian Marketplace.
