Amazon copyright restrictions
My ebook finally appeared on Amazon but when people are attempting to purchase it, they are getting this error message: "Due to copyright restrictions, the Kindle title you're trying to purchase is not available in your country: United States"
Why on earth would my book not be available for sale in the US?? I've never had this issue when publishing through LuLu. How can this be fixed?
