Hello Brothers and Sisters,
I have a small automation which works perfectly. When user links to EPIC any TASK with link relation "is a paret" then i am checking if TASK has EPIC LINK = null. If yes then I update EPIC LINK of TASK with EPIC issue key.

What I am looking for.
I want to inform users in case when:
1. EPIC LINK was null and NOW its updated
2. EPIC LINK was NOT null so automation could NOT provide new value
What i am thinking is trigger after GREEN CIRCLE. It means if condition is MET send email1
If condition is NOT MET send email2. Sounds simple but i cannot figure out how to build such condition...
