Hotspots in html5 responsive don't seem to be working for me.
Created test destinations, both on same page as well as in sections on other pages through the hypertext pod. Specify named destination. newlink TheNameOfMyDestination (with a space between the two).
Created hotspot on the first page in the book with the hotspot mode selected and then pulling out either a text frame or rectangle tool, and then when the hotspot pod popped up selected the destination from the available markers.
Works perfectly when I export to pdf.
But not in HTML5 responsive.
Tested in a couple different layouts thinking that was it, but no, same result.
