Readit.buzz Magazine

The readit.buzz site appears to be slightly broken on mobile, at least on android (I've tested Chrome and Firefox).

The hamburger menu in the top left of the UI isn't responding to taps, and comparing with kbin.social it seems to take up less horizontal space as well (the kbin logo is further over to the left here).

I know they are supposed to be running the same version of kbin right now, but is it possible there's some customization here that's causing a bug?
