When a page style is set to “Right only”, and the previous page ends up as a right-page, an automatic Left page can be inserted when the document is exported to pdf.
What is the page style for that particular auto-inserted Left page?
It is now a completely blanc page, but I would like to format that page.
Right now you cannot set the style for automatically inserted blank pages. See this enhancement request:
Hi
Default value is Left Page style.
You can check by Right click SideBar▸Styles & Formatting pane▸Page Styles▸Right Page▸Modify▸Organizer tab▸Next Style
[EDIT]
I had not understood the question, sorry, the right answer is that of @RGB-es
