I can see differences with the modules responsive behaviour inside columns when the browser is at the small device width breakpoint. Sort of speak, all content it’s like in a one column width. Fine.
But i can’t see differences when browser is at the medium responsive breakpoint.
I tried some moduled and also the defaut templates within the plugin.
I’m not entirely sure I follow here. You can set the breakpoints in the global settings which configure those breakpoints site-wide. From there you can configure the individual column responsive settings within those main breakpoints if that makes sense. Does that help?
