I am on a Kobo Libra H2O and it looks really good. Even sideways, split into two pages like a traditional book it's great! Albeit a tad small, but that's on the Kobo, not on you. 😁

The only error I've seen from the book is in traditional "portrait" mode, sometimes these numbers on the right side overlap some of the words. I'm not sure what these numbers are. I haven't seen them in any other epubs. I also reduce my margins and stuff to cram more words onto the page, so that may be on me.

I hope me bringing up the errors didn't make you feel any more horrible about the state of the book lol. I just wanted to offer my services because you were lamenting the state it was released in and your prior comment mentioned a re-release. A released book stuck in editing hell is better than an unreleased book stuck in editing hell! 😅
