I was wondering if this version of Page Builder has the responsive settings within each row. Basically you can hide/show each row by selecting the responsive size. This is beneficial if you want to create different layouts based on desktop, tablet & mobile. I have seen this available with this page builder plugin on other Themes.
Yes, you could utilize the Responsive Settings to create a certain layout on Mobile and Desktop. We also utilize this on some of our demos, for example: https://jnews.io/default/ the sidebar will hide on Mobile. I don’t get your questions or issue you might have, could you elaborate it?
Under row settings there should be a responsive options tab. It allows you to hide/show the row per screen sizes. I don’t see that in the plugin within your Theme. Is that no longer available or could it be the plugin was not installed correctly.
