Not able to download the premium bonus content?
Just bought the premium edition of Tearmoon for the bonus content. I tried downloading the premium version to my kindle ap on my laptop but it not showing up.
I don’t use kindle myself, but did you remember to convert the epub file? IIRC it doesn’t natively accept epubs, you have to convert it to a mobi file with a program like Calibre.
Kindle app does not read epub files; limitation imposed by Amazon.
There are various applications that will convert between ebook types. I use Calibre, which is free and quite capable. Just converted two epubs to Kindle mobi files a few minutes ago, and shipped them off to Amazon to display on my Kindles.
For the PC, you can also use any number of readers that will directly access epub files.
