Inaccurate Shipping Cost for Multiple Packages

[nicolasddev]

Preconditions (*)

Magento v2.3 & 2.4

Steps to reproduce (*)

1. Configure any shipping method with a max_package_weight value.
2. Add multiple products to the shopping cart, making sure that multiple boxes are required based on the shipping method's maximum package weight.
3. Trigger the \Magento\Quote\Model\Quote\Address\RateCollectorInterface::collectRates() method either by requesting shipping estimates from the shopping cart or the checkout page, or programmatically through a third party module and use the getResult() method to obtain the rates.

Expected result (*)

The cost values should be accurate in relation to the estimates returned by the carrier.

Actual result (*)

Although the price values from the different packages are compiled properly, the cost values remain the ones returned for the first package only.

Hello @nicolasddev,

We have tried to reproduce the issue in Magento 2.4-develop branch but for us, the issue is not reproducible. We have tried to reproduce the issue via the UPS shipping method by following steps:

1. Set Maximum Package Weight:

2. Add Items to cart (added 50 items of a product in cart):

3. Estimated Shiping cost displays like below:

Let us know if we have missed anything in order to reproduce the issue.

Thanks
