Sharepoint 2016 approval workflow not updating approval status
Like many features in Share Point, workflows can be as customized and complex as you want them to be, but they don’t have to be.
In fact, creating a standard workflow is quite easy, thanks to the simplified tools and wizards in Share Point Designer.
The authorized person can define the people who need to approve the content when attaching the workflow to the list.
Once a person adds a list item, the workflow will start and request approval for each person defined earlier.
This can be confusing because when Content Approval is enabled on your library, a document doesn’t become visible to others until it’s published. To set an approval workflow, access the Document Library and click on Library Settings. Select Workflow Settings in the Permissions and Management settings.
