Which codec has the file in? ABS supports transcoding to make a file playable.
If you download the book it depends on your phone.
E.g. OPUS is not supported for iOS 18 for example. This is nothing ABS can fix nor change. You can reencode them to a proper format or use a phone that supports the codes properly
