Hi there Dani!
Sorry I took forever. I double-checked again with Storefront, and this time around I do see the “Buy Now” button with Storefront installed on the Staging website along with all the plugins activated.
So when switching to Storefront, I do see the “Buy Now” option now.
Here’s a link from the Staging website: https://www.epicmat.com/woocommerce-test/?product=ethereum-phone-wallpaper
What could be the problem in this case? The theme I’m using?
