Hi, we are interested to change the prices of the shipping service of more products we have in ebay. We use the BulkDataExchangeRequests api and the ReviseFixedPriceItemRequest call to make it, we upload the xml correcty to ebay but the prices of the shipping dont change. This is the code example:

 <?xml version="1.0" encoding="utf-8"?>
 <BulkDataExchangeRequests>
