I used to be able to use the following JQL in a non-SaaS version of JIRA:
"Epic Link" in childIssuesOf(insertJIRAKey)
With the upcoming removal of "Epic Link" to replace with 'Parent", I'm unable to use the 'childIssuesOf' part of JQL that will allow me to find grandchildren through a grandparent.
Has anyone solved this problem to find grandchildren through a grandparent that is happy to share the JQL please?
