How to search for all child issues of an epic in a next gen project?

[Mike Solomon]

In a classic project, I could search for all children by doing "Epic Link" = ABC-123 but in a next gen project, this doesn't seem to work. Has anyone found a way around this?

I would love to do that too, seems like something very basic that should be available...

I am also trying to do the same thing. I don't see any Epic from next gen project while creating a filter. Only epics from old gen projects appear. It seems to me that next gen Epic is actually not an Epic.

Came across the same problem. This might help you:

Thanks to the thread posted in the answer above, this worked for me for a next gen project:

parent = TEST-123
