If another app on your store is failing to modify items as expected, it's likely because it needs to control the Add to Cart process. By default, UpCart may interfere with that flow. Enabling this advanced setting tells UpCart to stop managing the Add to Cart behavior, allowing the other app to function properly.

When this setting is enabled, UpCart will no longer control the Add to Cart process.

This allows other apps, custom scripts, and your theme to fully modify the item as needed—without any interference from UpCart.

Important: By handing off control, other applications may also dictate what happens after an item is added to the cart. For example, an app might redirect customers to the default Shopify Cart Page instead of allowing the UpCart drawer to open.

Since UpCart is no longer involved, we cannot prevent this behavior.

This setting introduces a trade-off. Please ensure you thoroughly test the Add to Cart experience on your live store after enabling it.

When this setting is disabled, UpCart maintains full control over the Add to Cart process to ensure everything functions smoothly.

An added benefit is that UpCart can actively prevent other apps or scripts from redirecting customers to the Shopify Cart Page, keeping the cart experience consistent.
