GemPages Landing Page Builder

Everything seems to work fine, until you finish your design and realise that the desktop layout doesn't sync (pictures missing or different pictures added, sizing wrong, columns layout wrong, text different sizes) with the tab layout and mobile layout, which you have to go in and tweak individually, but then realise those tweaks do sync with the desktop layout, so you have to individually mark sections in the advanced tab one by one to not display on the desktop or tab layout if you're tweaking the mobile layout specifically. It's the weirdest workflow I've ever seen and suck up hours as you check each detail to see which ones synced and which ones didn't.
