I have 2 yahoo account. but when i am creating app through this account i still gets same error. but if create app using another account which is my test account, then it allows me to create app successfully. But there is a difference between both the accounts. Actually my test account which allows me to create app is already having some applications created.so now when i am trying to create app, it allows me. instead my another account which is not allowing me to create app is newer one in which there is not any app created before. So do anyone has any idea about this issue. Pls help me.
