Flourish plots don't display on some smartphone

[CiS-fp]

Hello,

I am responsable for a website with ~1 million views per year. We are happy with Flourish plots, but they don't display on some smartphones. For instance, with a Xiaomi Redmi 12 Android with Chrome. Instead it shows a grey rectangle with an unhappy face. Curiously, sometimes reloading the page does display the plots.

This is a serious problem for us since our site relies heavily on plots and we don't know how many of our visitors have this problem.

Thanks
