@HuiZSF it was actually fixed by @Prtksxna! But I would still like to make a change to the design of a sold out button. Go to https://wikimedia.myshopify.com/products/wikipedia-globe-sweats and try to add size M to your cart. The button will say "Sold out".
@violetto could we please change the color of a button to grey?

Please claim this task again if/when you plan to work on it (via Add Action... → Assign / Claim in the dropdown menu). Thanks!
