I used the font manager to download a font from google fonts, favourite it and used it in theme styles for typography. Works well.
I disable he google fonts in Bricks Settings - the favorite font is no longer rendered on frontend.
Again enable the google fonts in setting and checked the frontend. The fonts are there , but the issue is there are not actually using the downloaded fonts, as this website still shows google connection when using the favourite fonts - Google Fonts Checker | Fonts Plugin
