Hello everyone!

I apologize if something like this has been posted before, as it will probably have been. But I'd really appreciate personal guidance with this.

I'm working on editing an epub for professional publishing. I'm using the aggregator Draft2Digital to publish the epub on several retailers at once.

However, on several of those retailers (especially Rakuten/Kobo and Thalia), the output of the previews leaves a lot to be desired.

On Thalia, the typeface displayed becomes the default (Arial) instead of our chosen typeface.
On Rakuten/Kobo, the typeface is preserved, but the chapter heading breaks up (chapter heading on one page, chapter text on another page!). It's even worse with the title page: the author name on one page, the title on another page, etc.

I see that other books manage to look perfectly fine on these retailers.

And when I read the ebook on calibre or when I import it myself into Apple Books, it looks fine.

Could you give me pointers with calibre on how to:
– Make sure the title page elements (book title, author name, publisher name, publisher logo) remain on one page and don't get broken up on several pages?
– Make sure the chapter headings remain together with the chapter text on one page?
– Force the display of our chosen typeface?

Thank you very much in advance for your help.
