To move a page, go to the Manager in your Yearbook Editor and expand the section that the page is in.
To expand a section, click on the section:
Once there, hover over the spread (identified by the page ID at the bottom of the thumbnail, which you can find in the print edition) and drag and drop the spread by clicking on the 6 dots in the upper left corner of the thumbnail.
You are also able to move the spread within sections and between sections using the same method! To expand all sections to move the spread throughout the page, click on "Expand All Sections" at the bottom.
You have successfully moved your spread!
