Hi There,
I have portfolio epic and want to add Epic as child issue to it.
The same I can do when I do it by dragging and dropping in portfolio plan (Advanced roadmap)
And it appears as below:
As Portfolio Epic shows:
Child issues:
and epic is displayed under it,
but when I link it with Epic through is is child task of,
it appears in linked issues and not in child issues, which then not reflected in advanced roadmap.

As the DOSA-15 is linked using link issues, but DOSA-13 has been dragged and dropped in advanced roadmap and it appeared as Child Issues in this Portfolio Epic,
how can I do this manually in Jira, instead of Advanced Roadmap?
