What is Document Inbox View in PromoMats?
The Document Inbox view functions like a filter to narrow the list of unclassified documents that a user has access to.
These documents also appear in other views, but the Document Inbox view must be open in order to select and classify multiple documents at once.
The Document Inbox view only displays in the Library Tab when a user is the owner of at least one unclassified document.
