I have an Epic XX-123 and i see the Stories and Tasks associated to the Epic XX-123. I also want to see the subtasks for the Stories/Tasks that have that certain Epic XX-123. I can't us an add-on and its not online version.
I am using a Kanban board that pulls the all Stories and Tasks, so the following works;
type != Epic and "Epic Link" = XX-123
Now I want to see the subtasks and i use;
or issuetype in subTaskIssueTypes()
But this shows all subtasks that are and are not related to the EPIC XX-123
