Amazon have announced today that there are some problems with Kindle book service.
“At this time, customers who have purchased a Kindle book cannot automatically download the revised content. Our technical team is aware of this issue and working to automate this process.”
The Kindle system is supposed to offer customers the opportunity to update their Kindles when publishers and authors update or revise the book files on the amazon system. This doesn’t affect new customers of books though.
“Please be assured that, the latest version of your title is what is currently available for sale on our website; hence, customers will receive the updated version only.”
