Your website shows your logo in the browser tab

Your Seascape website now shows your own icon in the browser tab, instead of Seascape's.

The Favicon you pick — on the Site tab of the website editor. It's your website's icon in the browser tab and on a phone's home screen.
No favicon? — your logo is used if it's square; otherwise the first letter of your shop's name on your main colour, so it always looks like yours.
