Beta 2 - iPhone - BrowserSync not refreshing styles on save

I’m using a fresh install of beta 2, just edited some styles and the styles are refreshed normally on the desktop.

On mobile Safari, though, when I change styles, I see the normal messaging “Rebuilding” and “Webpack built x in 834ms”, but the browser doesn’t actually update the styles. If I refresh the page on mobile Safari, the styles are updated, but that kind of defeats the purpose of browsersync.

I tried downgrading browsersync to 2.17.5, but no dice. Anyone have any ideas on this?
