Is it just me, or do most of the figures not show up in the PDF of the Optimization Coaching paper? http://www.ccs.neu.edu/home/stamourv/papers/optimization-coaching.pdf (I’m using the built-in PDF viewer on macOS 10.14.6).

Ah—I tried opening it in Chrome’s PDF viewer, and they show up there. Strange!

I have a really difficult time printing that paper on real paper. IIRC, only the first paragraph appears and the rest is blank.
