G pay and Apple pay showing incorrect shipping cost for the purchaser address

Background 

My business is located in the North Island of New Zealand.

My website has been running successfully for many years with different shipping zones set up for the different countries as well as different regions within New Zealand.

For the example below: The shipping cost; to have an item delivered to the north Island of New Zealand should be $50.00 NZD.  But to have that same item delivered to a country that I don’t have a specific cost of shipping setup for (rest of world cost) would be $172.00 NZD.

Google pay and Apple pay showing incorrect shipping cost for the the purchaser address 

• Within Google pay, After selecting a New Zealand shipping address. Google pay still shows the “Rest of world” shipping cost of $172

• Even if you go into the Cart and manually select the Country and Region to get the correct shipping cost displayed in the cart. If you then select Google pay as your payment option, The shipping cost in will revert back (after 1 second) to the “Rest of world” shipping cost of $172?

• The same issue happens in Apple Pay?

Notes

• All themes and Plugins up to date as of October 2024.
