I am trying to change the cover picture for ebooks on my kobo glo. I have changed the picture using calibre and the new picture shows up in the calibre library and on the tile of the home screen of my kobo glo. However, when I open the book to read it, on both calibre on my computer, and on Glo, the old cover picture still shows. I have closed both calibre and glo and restarted both, but still they are showing the old cover picture. Any ideas on what is happening please guys? Thanks in advance.
