After you have located and added your PDF, you will then receive a popup box with two options.
Option 1: Update Issue
This option will replace only the pages of the issue while retaining all interactive features and existing published link. Choose this to correct errors in original PDF. The new PDF needs to maintain the same number of pages and layout.
Option 2: Redo Issue
