Favicon and Webclip Do Not Update

I changed my favicon and Web Clip months ago to reflect a change in my logo but neither of them changed. They still both show up as the old versions, after I uploaded the same images again and hit the publish button.

From Webflow I click on settings for my site, bringing me to the page that lets me change them. Both images show themselves to be up-to-date here, but both the favicon in the tab on my computer and the webclip on my iPhone still show the old version.

What reason could there be for these not changing? Even the SEO’s updated itself since I last checked, and that was a more recent change!

Did you figure this out? It is happening to me also
