I created an interactive PDF in Acrobat with footnote links and back buttons for figures referenced in the text. It's on my site as a download and it works fine when downloaded to desktop but when downloaded to a mobile device the links and back buttons no longer work. I've read that native mobile pdf viewers don't render interactive elements very well if at all but I was wondering if anyone knows of a workaround for this?

Not all PDF readers support all PDF features, so the simpler you make a PDF the more it will work as expected.
I did not see anything wrong with any Links (please update your question to provide a specific link not working).
As for the "Back" buttons, I can see that they do not follow the PDF standard. On page 14 you have a
Widget annotation, with a
A action with the following info.
S is correct, but the
N is not, it should be
PrevPage. See the
Named actions table in the PDF specification.
I edited your PDF so that particular "Back" button on page 14 used
PrevPage instead of
GoBack and it worked as expected.
So for the "Back" buttons at least you should review how you created the PDF.
However, my real suggestion would be to just remove the "Back" buttons. PDF viewing software provides better/easier ways for users to navigate pages of a PDF, than clicking on a button on the page (which may not even be visible depending on zoom).
