I'm trying to set up a workflow for document approval using (what I think are) the default workflows provided in SharePoint. After I set up the workflow and go to a document to initiate it, the approvers field is missing and cannot be edited (see image below). I can edit this field in the workflow setting and assign people but I want to be able to be able assign people when stating the workflow. I have tried to figure out what has is causing the but no luck.
Hoping someone is able to help!
