I've just downloaded the trial version for Lightroom CC to try and experience with the book module.
It seems I have a different layout that the one shown in the tutorials, so I'm missing the "Book" tab on the top-right of the screen.
Do I need to externally download this module? Is it unavailable in the trial version?
Would appreciate some help,
Lightroom CC does not have the same layout as of the Lightroom Classic CC and the Book module is not available in Lightroom CC.
