The print version is ready to go but everything has ground to a halt in Amazon.  The problems started when I tried to upload a revised cover for the book.  It uploaded without trouble but I cannot go any further as it is asking me to both review the book and enter an ISBN but the fields to do this are both greyed out.  I have been on to KDP help but apart from friendly answers promising to investigate, nothing is happening. It has been like this for nearly a week.  Grrrr…
