My back cover has no text on it. How do I add the book description and my bio?

Update to version 1.9.17. Under the back cover on the book's page there is a "Text" button. It opens a dialog with a tick "Put the description and the author bio on the back cover", the book description, and the bio. Click "Write it with AI" to have the description drafted from your book (110 to 160 words, in the book's language, no invented praise), or type your own. The bio comes from your author profile, or from the book's own About the Author if you edited one, and you can change it for this cover. BookyAI sets the words over the artwork itself, so everything is spelled exactly as you wrote it, accents included, with a space kept free for the barcode. For a back cover made before this version, open "Text", fill it in and save: the words are added over your existing artwork.
