Books and exporting highlights

Ok MPU Fam,

I read on Books, highlight, and export my highlights via Mail. In the notes section (when using my iPad or iPhone), Books typically offers me the ebook page and often I can hit a link to change it to provide the print book page numbers for each highlight.

Last night, I exported highlights from two books. One came over no problem, the other only gave page numbers for the first chapter, but none after. I’ve tried exporting on both of my iOS devices (iPhone 11 and older iPad Air2), same result.

Any tips? Any other readers for epub formatted books? I hate Kindle… but am open. Especially if I can export my highlights.
