Hi, For the past few days I'm unable to retrieve authentication token. Although I have authenticated with ebay several times using the url
https://signin.ebay.com/ws/eBayISAPI.dll?SignIn&RUName=RUName&SessID=SessionID, all calls fail with error: "21916017 ERROR: The end user has not completed Auth & Auth sign in flow." It used to work perfectly a week ago, but now it always fails. Any known issues with this API? Can someone please confirm if this call works? Thanks!
