Hello @Md Yeanus,

Welcome to the Klaviyo Community!

If you haven’t already, I would recommend taking a look at the Community posts I’ve linked below that cover a similar subject.

One thing you’ll want to be aware of is that the installation of the code may differ depending on the configuration of your Shopify store. Since this does pertain to installing code on your website, I would recommend working with a developer to review the correct installation methods for your site. 

I also noticed that it doesn’t appear that the Viewed Product metric was triggering when testing despite having the Klaviyo app embed enabled. I would recommend double checking in on this first and ensuring your Viewed Product event is firing since these two metrics are tied in close relations with one another. Without the Viewed Product event triggering first, the Add to Cart metric - even if installed correctly - would not fire. This can be caused by a number of things, but most commonly due to having duplicate Klaviyo.js installed on your site as mentioned in one of the posts above. 

I hope this helps!

David
