Using Quickship has greatly sped things up in our order processing, but we occasionally encounter issues with warnings being hidden. For example, If an order is canceled by the customer while it is in the process of being picked/shipped, it can still be shipped out since the canceled warning is hidden by using Quickship. This results in additional work and costs for us.
There is a long list of potential errors that are hidden by using Quickship: https://help.shipstation.com/hc/en-us/articles/208740268-How-do-I-skip-the-warnings-I-get-while-I-m-creating-a-shipping-label-
It would be nice to be able to either have the ability to select warnings to handle as errors or at least have some visible warning appear.
