Key points
Every workflow can have one draft version in development
Published workflows cannot be rolled back
Workflows can be unpublished to stop execution
Workflow states
Draft: Development version of a workflow
If you have a draft working for a published workflow, it will be designated on the workflow homescreen.
Published: Live version that executes as configured
Unpublished: Previously published workflow that is now inactive
To unpublish a workflow, click into the workflow, click the three dots in the top right, and click unpublish
Notes
Only one draft can exist at a time
Once published, changes require creating a new draft
Unpublishing preserves the workflow configuration while stopping execution
