To edit an item in the Content Center you will need to be the item owner or a company admin, otherwise you can only preview the item.
1. Navigate to the Content Center.
2. Hover over the the item you want to edit and click the 3 dots on the right and choose Edit.
3. Make the edits needed.
Note: Any changes made to the content itself - the URL or the uploaded File changed - it will propagate to the item on all boards it's associated with.
All metadata information (items’ title, description and image) changes will not propagate, and the changes will only be made to Content Center piece.
Notice you can choose to make the item private, making it available only to you from the private list.
4. Save changes.
