I'm creating a fixed-format children's book in Sigil intended for all kindle devices plus iBooks later.
My manually created TOC works fine on Kindle Fire. On ordinary kindle, the links don't work, search isn't an option and link to TOC not functioning either.
Does fixed-format kill functions on older devices.
Kindle has been updated recently.
From Sigil, I use Kindle Previewer.

As an experiment, I used Calibre to create an AZW3. Link, search etc work, but it kills the fixed format.

Also, this needs to be sold on Amazon. So i need to sue acceptable format.

Thanks.
