Hi Guys. If reading this on your phone (which I recommend), use your browser — not the medium app.
For whatever reason, the Medium app stops loading the artwork/cinemagraphs/gifs/whatever at the halfway point.
Viewing in mobile Safari — no such problem.
I filed a bug with Your Friends @ Medium some time ago. It’s unlikely that Medium will devote developer resources for the work of one writer. No worries — enjoy on your phone’s browser, or on your computer.
