I designed a document with a pre-built, A4 layout template. The client has since changed the document to 8.5" x 11". After doing this I had to move things around a bit to get them aligned inside of the new space. The one thing I cannot figure out how to nudge are page numbers. The numbers are correct... I just don't like where they rest on the page. Where do I go to nudge them up and down, left and right?
Open your pages panel (Windows > Pages).
Up the top you will see the page masters.
Double-click on the relevant master page and you should find the page numbers there.
Changes made to a master page get replicated to all pages with that master applied.
If you can't select the page numbers — check your layers panel to ensure they're not on a locked layer.
