Is this the favicon you have uploaded into your theme under Online Store > Themes > Customize > Theme Settings > Favicon?
If not, let me know and I'll reach out to you directly to help further!
Can you please provide a screenshot of where you expect to see your Favicon appear?
Also, if you can let me know your store's URL that would be very helpful.
Thanks so much!
Thanks, @Bearse !
I can see your favicon is working as expected:
When a favicon is added through your Shopify theme, you should see it within your browser tabs, as well as on browser pages that list web addresses such as the bookmarks page, not within your Google search listing.
Let me know if this helps!
