Presenter (360) published file doesn't support links... but powerpoint slideshow works fine

I have a powerpoint file (upgraded from presenter 13) now in Presenter (360) where when I preview the slides -- the hyperlinks I created work just fine.  It's worked for years in presenter 13 and it a huge project I invested tens of thousands of dollars in labor in over the last 7 years or so.

Now when I use presenter 360 -- the linking is broken (which is at the core of this 200 slide utility that I built).  AGAIN (this is important)  when I view the slideshow in articulate it works fine an navigation is flawless. But as soon as I publish it to HTML5 in the "LMS" configuration, only the first jump works, none of the subsequent links work.  Any ideas?  I did talk to a support engineer a couple years ago on this when 360 first came out and he said "oh, we don't support that..." but that's not true -- there are Articulate tutorials showing (as they called it "branching") it working just fine.  So it's been a year or two and I need to update this content, so I'm back trying to figure a solution, again.
