In Spotler you always first change the status from Final to Draft or Test to be able to edit. This is a piece of built-in security, so that you are aware that your change can have an impact.
Keep in mind that when you change your automation, these changes are not reflected in your publication. You will have to republish the automation and stop the old publication. Messages, forms, web pages and surveys are in principle separate from your automation and publication. You can therefore change this without any follow-up actions.
