I want the user to be able to go back and forth on any of these pages. And this is all pdf pages, and the important thing is the hierarchy. In the sales order we are informing how much we will charge on specific usage, so if users have any doubt regarding the invoice charge, they can browse the sales order page to confirm the charges. And if they have any doubts regarding the terms and agreements, they can jump to the page 1 service agreement. These are the internal link docs.
While designing the experience, I thought breadcrumbs was the best option, but the issue is can't hide the last page in hierarchy because these are all pdf files with no way to link from the content. Is this the right approach to do this?
The user will come to this page from the invoice table, so the last page of invoice will appear first when the user taps on the invoice from the table view.
