So I've created a mobi with nested toc from html.
In the calibre ebook viewer the toc is displayed exactly as it should be:
Chapter 1
Chapter 1.1
Chapter 1.2
Chapter 2
...
However, on the Kindle Paperwhite the toc appears flattened:
Chapter1
Chapter 1.1
Chapter 1.2
Chapter 2
...
Now I know for a fact that the device supports nested toc in mobi files as it works in purchased books, so I guess there must be a problem either with the conversion process or on the kindle side.
I'd appreciate any ideas on how this could be fixed, it's very annoying.
Thanks in advance
edit:
I should specify that it's the metadata toc I'm talking about, which I just learned is implemented in mobi as a content toc at the end of the book.
I checked, and the latter, when accessed manually, is displayed correctly.
It's only when viewed with the GoTo button that the toc is flattened.
Very strange.
