That minor issue is still there only when viewing on Google’s Chrome browser for my iPhone 6. It’s running fine in Safari.
Also, from mobile view, the homepage where we have the masterslider is getting cutoff. It appears to be similar to how the subheader was getting overlapped by the main header. maybe the same tweak you made to the regular pages needs to happen there too.
Also, the main header floats down when you are scrolling down on a page in mobile view. It seems to go a long for the ride when it should stay at the top.
