There is an issue with the background-color of the submenu in Twenty Twenty-One.
For some mysterious reason, the background-color of the submenu hasn’t changed according to the color settings of the theme. The theme’s background-color is set to some kind of orange or light brown; the background-color of the submenu is still turquoise.
To make things more complicated, the bug doesn’t always reveal itself.
Is there a way to fix this?
Thanks in advance,

I’m not sure if this is related, but I did notice you’re missing a closing curly bracket } at the end of your custom CSS, which can sometimes throw off other CSS, such as the CSS code which is included in your site when you change the background colour in the Customizer.
As a first step, could you please try adding a closing curly bracket at the end of your last piece of Custom CSS in Appearance > Customize > Additional CSS, and let me know what happens?
