But the theme does not actually require a paid version of the plugin. The whole theme demo website was built using the free version of Beaver Builder, as stated on ThemeForest page too. I leave upgrade decision solely up to theme users depending on their needs.
Also, it is considered a bad practice to include paid versions of plugins with themes (I’ve learned my lesson in the past…). I’m sorry if you expected a paid version of Beaver Builder included with the theme, but there must be a misunderstanding as I do not state such plugin inclusion anywhere in the theme description. All plugins recommended by my themes are free. Upgrade to your own convenience.
