I honestly can't believe this hasn't been fixed yet. I have paid Squarespace hundreds of dollars and spent months creating a site in fluid engine with good consistent spacing in both desktop and in mobile view using the mobile editor. But when I view the site in mobile and turn my phone to landscape orientation (as many people may do when looking at my site), the spacing adds large gaps above some section headings and not above others. It looks amateurish and unintentional.
The comments above were from last July! I'm about to make my site viewable to the public and when I reached customer service about this, they said they had no update or eta on a fix to this "larger issue" and they would add my complaint to the report. How about offering me all of my money and time back instead! Unbelievable.
