I cannot understand how one goes about configuring Jira even at what should be the simplest level using the built-in features. In other words, I'm not down in the weeds trying to write scripts. I wanted to add a level of functionality to our business project by implementing the Epic issue type. That done, I created an issue in the Epic. It doesn't "link" up with the main Epic issue. As shown below, Issues in this epic is empty. Also, I am unable to show the related epic on the created issue screen with no easy way to make it visible.
Why is this confusing method of setting up this system so pervasive? I try to modify something in a project and suddenly I find I have modified some globally linked screen or whatever which affects every other project that uses it. There are no guardrails to keep you from screwing up stuff and no decent documentation to help.
I would like for someone to explain or point me to a better "tutorial" than what I've been able to find so far.
OK, rant over.
