We are using 2 level hierarchy - EPIC and TASK in our JIRA. We are looking to link multiple tasks/issues to a task to ensure completion of a parent issue should be blocked by Linked issues completion.
We understand that this can be done through automation.
However, the issue is how to VIEW these linked issues in a tree/hierarchy structure in JIRA?
We are not currently looking to install any 3rd party PAID application due to pricing constraints.
