I am using two types of Exports: EPUB and PDF. The PDF version displays as expected with 1 column but the EPUB version displays as 2 columns, resulting in some images being superimposed over the next column’s text and others running off the right margin.
I am viewing the EPUB export using Adobe Digital Editions.
@jdelargy This sounds to me like it may be a display setting with your reading software (Adobe Digital Editions). You may want to try a different reader that provides you with more display options, or check the Adobe forums to see if there are any suggestions/solutions that can help you with your book. Good luck!
