Starting yesterday at 11:25am MST when uploading a listing revision with ReviseFixedPriceItem the API is returning the error:
PostageCostPaidByOption is required. It has been defaulted to buyer.
Bearing in mind that our listing management system has been working faultlessly for years I find it really unusual that this error has cropped up out of the blue.
There is no reference to the option in the ReviseFixedPriceItem documentation and googling the error returns no significant results.
Any comments or suggestions would be appreciated.
