I am working with MediaVine for advertisements and I just switched to your theme (live today after a month of testing).
Currently, it appears to go full width at 768px and MediaVine is requesting a change to make it happen at 999px. Is that customizable? I am trying to avoid changing the parent theme or to copy everything into the child theme.
I am willing to wait for an update to the theme if that could be an option.
I am basically trying to go with the full content spacing as with mobile once it reaches 999px. Tablet and Mobile to have full content view and and drop the columns.
