Hello, im trying to edit the site styles in my squarespace template. the button does not respond and the features does fails to provide the side bar window to make edits. im not sure why this is. when i copied the site it allowed me to use the site styles button. however on my published site while attempting to make edits it does not respond. The image below shwos the brush icon for the site syles. it is located in the site editor at the top right.
