How can I get the the same format for pages before the TOC?
The "format is set by the template you use. You have to decide if you use the template in its default setting or make changed You can change fosts and colour on the page, but ideally you should really edit the template
and change fonts ,size,colours Styles in order they flow through the book. Decide if your book is all landscape or all portrait mode, if you want both, need to change modes and edit accordingly.
I opened the "Basic" template and tried to replicate your actions, The top four items in the tree - Book Title, Intro Media, Table of Contents, Glosssary; dont allow me to drop anything, so I assumed you mean to drag the page up the tree. Under "Glossary" is a column width separater line, dragging the copyright page up will eventually show a blue line appear inder the separator line. Drop the page.
I do this in every book I create to have the Copyright page show as the first page opened by a reader.
The page content is exactly as it is laid out in the template.
If you wish only landscape mode, open the Inspector, select the book icon on the top left and at the bottom, tick the box for "Disable Portrait Orientation.
Did you change your chosen template in any way?
Did you replicate your actions in another template?
