If for some reason, you need to unpublish your story, don't panic.
That's all covered in Story Chief.
Click on 'Stories' in the navigation bar and you will see the your stories overview page.
Your article has 2 states:
- Published: Is live and visible for public on channels you've published to
Click on the arrow next to 'view report' of a story and then click on 'unpublish'.
Some channels won't allow you to unpublish via Story Chief like ambassadors (since they already received an email) or LinkedIn (you have to remove the post on LinkedIn itself).
