View_item and add_to_cart events do not work when integrated with Shopify in GTM preview

[Salamud]

Hi!

Set up eCommerce in GA4 through a standard integration. 

Selected Google Channel app in app settings, connected Google Ads account.

When you connect this integration, usually the data layer data is automatically transferred to GTM.

When checking events through GTM preview, I found that view_item, add_to_card events do not work on all items.

Sometimes the events work, sometimes they don't. More often they don't work. And as I noticed it does not apply to specific items.

Since on the same product sometimes events can work and sometimes not.

If the ecommerce events don't always work, we can't track performance in GA4 and we lose data.

Who knows what the problem is? How to solve it?
