New to Jira so forgive me if I'm missing an obvious reference guide somewhere.
I am trying to automate the timeline/due date for subtask that are created when triggered but can't quite get the syntax of the command correct and can't find the correct reference for it.
For tasks non depedant on another task I have the start date as "Start date from Curruent Issue" which works fine, but how do I then say the due date is start date +3 business days. Currently I have {{Issue.Start date.plus business days(3)}} but it doesnt seem to do anything.
Additionally for start date variabilty, how would I reference the due date of a previous sub-task as a start date for a new subtask?
