I read mobi books on several different devices (esp my laptop and my kindle.)
I was very excited to see that calibre was setting an ASIN by default so that kindle software would now update my location across devices (as mentioned in the changelog entry referencing this bug
http://bugs.calibre-ebook.com/ticket/8721).
I tested it, and it worked perfectly.
Now, I'd love to have this feature for the 200+ mobi books I've already converted using calibre. Is there any way to update them all at once, or do I need to regenerate them all manually (what I did with the book I tested it on.)
Thanks in advance for any help.
