I've been using the ShoppingAPI GetSingleItem for years.
Recently, there are some items that I couldn't get PaymentMethods correctly.
for example:
got correctly:
https://www.ebay.com/itm/184652316112
https://www.ebay.com/itm/363284007536
couldn't get (empty):
https://www.ebay.com/itm/254857776168
https://www.ebay.com/itm/293996428163
What's the difference? How can I get PaymentMethods correctly on those items?
I'd appreciate any hints...
