I am having an odd issue with the USPS shipping plugin. I only have one shipping method published, Priority Mail, and it is properly fetching shipping rates. However, during checkout, if I change the address that the order is being shipped to, the shipping rate is updated as it should be, but the shipping fee in the cart at the bottom of the checkout page does not update. It still shows the old rate. If I add in other shipping options, parcel post and express mail, I can switch to one of those from priority mail and the shipping fee at the bottom of the page is updated. If I then switch back to priority mail, the correct fee appears at the bottom.
The shipping fee is just not updating when the address is changed.
Has anyone else seen this? Anyone have a work around for this?
