Removing ebook from Kindle
I've chosen to remove Kindle distribution from my book, which has been published since June 2015. About a month ago, I unchecked the box on the Distribution page. However, the ebook edition still appears on Amazon. Is it normal for it to take this long to get out of the Amazon system, or is there something else I should be doing?
