I've created an application. I have setup app id, dev id and cert id. I have also created a new sanbox user. When I try to create a sandbox user token, it doesnot work. I can sign-in while trying to create a oauth token, after pressing "I agree" it doesnot retrieve the OAuth token I have setup "Your eBay Sign-in Settings". I can get "Auth'n'Auth" but not "OAuth (new security)"
