To duplicate pages:
On the Pages panel, do one of the following:
- Tap the thumbnail of a page (or master page) to make it the active page, then tap Duplicate. (Alternatively, long press the thumbnail and select Duplicate. The duplicate page is added after the active page.
- Tap Manage Pages or Manage Masters, tap the pages you want to duplicate (so each displays a check mark, meaning they are selected), then tap Duplicate. The duplicate pages are added after the last page in the selection.
The new pages can be arranged wherever you need them in the document via Manage Pages (or Manage Masters).
