Epub created but TOC does not appear in downloaded version
Thank you Mr. Lomas and Daniel for previous assistance.
I successfully formatted With different computer and epub was created, showed TOC and I proceeded to upload customized cover for ebook.
However, once completed, I downloaded to review both interior and image for cover.
TOC does not appear in manuscript even though it previously appears after uploading manuscript and converting to epub.
I did choose to make it only view to me and then I would change that later.
Does anyone have suggestions as to why I do not see TOC in downloaded epub?
