Hi,

The problem because that Google Bots can't read the CSS files of your site, so this will warn your page will not be friendly for mobile. You can view similar issues here: https://support.google.com/webmasters/thread/31643008/how-to-fix-incorrect-mobile-friendly-test-screenshot-mobile-usability-errors?hl=en

You can get the correct result by checking your site on a 3rd service like: https://sitechecker.pro/mobile-friendly-test or https://ready.mobi/

Hi,

You should check the robots.txt content of your site, make sure the search engine bot can read the CSS files then check again.
