Hi!
I have created a Kanban next-gen project and set up an automation rule than transitions subtasks of a story meeting some criteria and sets some fields like assignee and start date.
The transitions went smooth yet the fields weren't updated. I think the possible reason behind this is that I am not seeing the Automation App User in any permission-related site.
I keep getting this error message:
Unknown fields set during transition. Field may not be on transition screen. Fields ignored - Assignee (assignee), Start date (customfield_10015).
By the way, I have a free plan, I don't know if that affects the issue.
