Responsive breakpoints broken

Hi guys. We noticed in the latest update that there is weird behavior happening with mobile breakpoints between 600-900px. At around 800 px we are seeing a spot where the mobile nav AND the desktop nav are showing simultaneously (this is happening on your demo theme as well as our site.) Also our logo is getting squashed miniscule at around 800px…

Below 700 it seems to just snap the body into phone view and shows 1 narrow column now too instead of a nicer tablet view. I could swear it had bvetter tablet layout in the old version…
