So I'm knew with this shopify app called "Buy button", but managed to add to my items collection. Anyways, zoom on the product while holding the mouse on it is not disponible, the issue is something else.
I have configured my own domain to my shop, but when going to checkout using the Buy Button app will show in the link bar the adress with shop.myshopify...
Does anyone know why it is different then when using the shopify default cart and shopping system? With it it will go with my own domain displayed.
