Duplicate "Add to Cart" Event and Multiple "Add to Cart" and "Remove from Cart" Events Triggered by Shipping Calculation

[vitorwell]

Description I am experiencing two issues in my Shopify store:

• Duplicate "Add to Cart" Event: When the "Add to Cart" button is clicked, the "add to cart" event is triggered twice.
• Multiple "Add to Cart" and "Remove from Cart" Events: When calculating shipping on the product page using the Smart Shipping Calculation plugin, multiple "add to cart" and "remove from cart" events are fired.

Steps to Reproduce

• Navigate to a product page.
• Click the "Add to Cart" button.
• Observe the tag assistant requests to see that the "add to cart" event is triggered twice.

To reproduce the second issue:

• Navigate to a product page.
• Use the Smart Shipping Calculation plugin to calculate shipping.
• Observe the network requests or event logs to see multiple "add to cart" and "remove from cart" events being fired.

Expected Behavior

• The "Add to Cart" button should trigger the "add to cart" event only once.

• Calculating shipping should not trigger any "add to cart" or "remove from cart" events.

  Actual Behavior

• Clicking the "Add to Cart" button triggers the "add to cart" event twice.
• Calculating shipping triggers multiple "add to cart" and "remove from cart" events.

Environment

• Theme: Dawn
• Theme Version: 13
• Shipping Plugin: Smart Shipping Calculation

Please let me know if any additional information is required.

If you see duplicate add_to_cart events or any other duplicate event, first make sure you don't have any apps like "Google & YouTube" that could be responsible for those events.

In almost all cases, I have found that when there is a duplicate event, one of the events is coming from the "Google & YouTube" app.

So, before discussing further, can you add an event prefix and test it?
