Quote styling not pulling through to browser

I’m guessing you’re referring to this theme: https://wordpress.org/themes/biggroup/

I tested it briefly on my end and didn’t find any issues with the Quote Block, which I assume is the one you’re referring to: https://wordpress.org/documentation/article/quote-block/

So here are a few tips for you:

• Try switching browsers. Can you see it in a different one?
• Try deactivating all plugins to rule them out as the cause.
• Try switching the theme to TwentyTwentyFive – can you see it then?
• If you have further questions, it’s best to contact the theme’s support forum: https://wordpress.org/support/theme/biggroup/
