Longform-PRO – mobile menu/chapters

Greetings,

When on MOBILE device (cell phone) I did not have a MENU, so after research, this solution came up:

.modify .site-header {
visibility: visible;
opacity: 1;
position: fixed;
top: 0px;
left: 0px;
}

NOW, I still seem to have problem with the CHAPTER LISTING as on desktop it “automatically pops into affect after one has scrolled past the title/1st object”. on MOBILE, there is no MENU/CHAPTER OPTION.

Item in question: http://imersivmedia.org/xs/the-xukuru-story-mobile/ (please, access only via cell devices WIFI – save 4g bandwidth! if you go via desktop you will not experience the problem)

Please help, can’t install my script until this has been resolved. (website is live as of SAT OCT 15 2016). We are a non-profit trying to get the word/story out regarding 3rd world situations.
