Live Preview is not getting CSS classes from framework

Hi!

I can’t get the Live Preview to work on the desktop version. I watched the video and followed the instructions on the documentation page, but I can’t see my classes and variables from the Core Framework in Pinegrow. I also tried with AutomaticCSS, but without any success. All plugins, including the one I’m building with Pinegrow, are active and updated.

The test live connection was completed successfully, and I’m able to get general live data like the site title and description.

Apparently, it’s just the CSS framework that isn’t syncing. What am I missing?
