I generated responsive HTML output; however, I do not see the "Next" and Previous" icons visible in the output next to Print icon. I used all the 3 layouts. The icons are enabled in the layout. Is this a known bug?
Did you create a sequence and added it to the output? As far as I know, these icons are only displayed in topics that are part of a sequence.
A sequence of topics that should be displayed one after the other. Sequences are used to guide the user through any order of topics that seem fit. And only for topics that are part of a sequence, the next/previous icons are displayed. In the screenshot you can see where to define sequences.
