The Viking Dragon

Cannot send orders to the USA any more, as keeps saying "Duty amount cannot be zero". I am using the MPR option and It was absolutely fine until Monday 24th November and then this issue started. I have contacted the help team and technical department and no one has helped me at all. I have sent screenshots of issues and got no reply. At present I am having to send all parcels manually through send.royalmail.com, which is far from convenient when I have to enter all details manually. I have tried clearing my cache, using a different browser and deleting the app, but so far nothing has worked. Works fine for all other countries

Optimized, watermarked and inputted alt text in over 800 images in less than an hour. Saved me a couple of days or more of doing this all myself, so very pleased with the results!
