Hi,

How can you register the button ?

Did it register by app or customize in code directly?

Hi, I already registered the button and Amazon gave me the code, but I don’t know which file I should put. Because I was used Turbo theme before, we changed the theme then this button is gone. I tried to use App, it can’t do that. It should use code add on. Could you help me?

{% if product.sku %}

{% else %}
{% endif %}

Hi,

I think you need to copy the code above and paste to new theme where you need it appear.
