Downloaded Audio chapters out of order.

Samsung A32
I downloaded The Saints volume one. When I go to listen to the audio file, all of the chapters are unorganized.

There is no option to organize it by chapter. How do I fix it?
Where can I find the files on the android phone?

Thanks

The sort order of downloaded audio in Settings > Downloaded Media is inconsistent – it might be worth reporting this as a bug in Help > Send Feedback. However, as a workaround, you can go to the Saints book in the library and listen from there – open the chapter you want to start with, and tap the headphones icon to open the audio player. By default, when the audio for a chapter finishes, it will go on to the next, and it will be in the order the chapters appear in the book.
