Amazon’s wheels grind slowly, but they do move. This morning, customer support responded to my trouble ticket:
Normally it takes 7 business days to send the updated content, but in this case, we will send the updated content to customers within 3 business days. We’ll notify you about this by the end of the day on “Tuesday, January 29”.Amazon.com firstname.lastname@example.org
Their math is a bit off. 3 business days from Thursday would be Monday, January 28, but I’m not going to argue the point. In a matter of days, the correct book will be on kindles!
