Hey, I have some custom ebooks I set up with covers. I added a cover.xhtml file so the cover loads first before any text in the book. This works fine in Calibre for all my books, but I use Apple Books to read on my iPhone, so no matter what storage service I use—Google Drive, Dropbox, etc.—sometimes the cover.xhtml file doesn't load, and it instead skips to the text. It's not all of my books, so I don't know what's going on. Anyone know how I can fix this?

I've attached, for example, 2 ePubs; Blood Oaths works just fine, whereas Nomad does not.
