When I registered a test user in sandbox environment, Access to Activitiy -> Sell -> Sell an item. It redirect to login page https://signin.sandbox.ebay.com/ws/eBayISAPI.dll?SignIn&UsingSSL...
After I login， It redirect to http://bulksell.sandbox.ebay.com/ws/eBayISAPI.dll?SingleList&sellingMode=AddItem
When I input the keyword, for example "skirt" in "Tell us what you're selling" text input, click the button "Get Started", a popup window appears "Looks like something's wrong. Please try again. ". When a click "OK" button. The page redirect to "https://signin.ebay.com/ws/eBayISAPI.dll?SignIn&UsingSSL=1&siteid=0&co_partnerId=2&pageType=2380680&ru=https%3A%2F%2Fwww.ebay.com%2Fsh%2Flst%2Factive".
Any problem happened?,
