Hi Kevin - thank you this seems to have done the trick.
I changed linear= to "yes" - is that what you had in mind.
TOC now shows in Apple Books
I also installed the epubcheck plugin which found a few html tags but also flagged that the css file linked to in nav.xhtml did not exist. So I created a new one and linked it.
So now I have no errors and will test again.
Thank you for the tips.
Jonathan
