New BB user. I searched and didn’t find any related posts.
I’m using a bare-bones starter theme (Sage v8.x). I’ve disabled the few plugins I have installed on this new site and the issues persist.
When using the Preview Layout view from the BB UI menu, I see my page with a gray background and a constant spinner (fl-builder-preview-mask).
I also noticed that in the Responsive Editing view I see the same gray background as above and all formatting from the text editor is lost - eg. default styling for H2, P, etc.
Is this the expected behavior for these views?
