Hi,
I need some clarification about EPUB exports. I’ve noticed that when exporting to EPUB, it exports the currently displayed rendition, unlike when exporting to an app. If I export an iPad-proportioned rendition and upload the book to Apple Books, what happens if someone downloads it on an iPhone with a different screen ratio? Will it automatically adjust?

I’d love to take advantage of the Apple Books Store in addition to the App Store, but I’m not sure what the best approach is. Any guidance would be appreciated!
