Plotly JS Download Image on iPhone

Hi there. I have not found any info on this so figured why not try here.
I am working on a project using Plotly.js as my graphing tool. When complete, I will be embedding this HTML/JS code on a website.

Plotly has a built in download plot functionality in the menu bar. This works on my computer, but when I load my website on iPhone, the download provides an error.

You can try for yourself on my test Google Site: Plotly Concept
Test it on your computer, and then on your iPhone.
Do you get an error on iPhone as well? Attached are some screenshots of what I get. Any help would be appreciated!!
