I am mobile and I have inertial scrolling. I think it is probably because you are using iOS safari. iOS' inertial scrolling for some reason breaks very often.

I am mobile and I have inertial scrolling. I think it is probably because you are using iOS safari. iOS' inertial scrolling for some reason breaks very often. It happened to my website a couple times, and I had to fix with a bunch of css hacks. Supporting iOS is just a pain. Sometimes, I would even rather support IE 11 than iOS. (btw, all iOS browsers are forced to use safari render engine.)
