Favicon not showing up in search?

My Favicon is not displaying in the google search results. It is just a white space. In the Yoast SEO Plugin preview, it shows my actual favicon. I’ve uploaded it to my WordPress site properly. It shows in the browser once you’re on the webpage. It simply doesn’t show in the search results. I’ve tried incognito mode, clearing the browser cache. It’s not just me. Any ideas?
