PlatformBase is not a mobile theme. It's the requisite child theme for PlatformPro. Think of PlatformPro as the engine and PlatformBase as the chassis. Normally, without and added software, plugins, themes... Platform is responsive in mobile devices.
That said, PageLines Framework is responsive with many add-ons, plugins, sections and child themes better designed for mobile than Platform ever was.
I'm sorry for the confusion. You'll likely not see any upgrade link in Platform for Framework that I know of, but you should take James' advice and write to firstname.lastname@example.org.Go to the full post
