Hi, From the developer account, I clicked on the "sign in" button, I was taken to the page with the "agree" button and after this I was taken back to the account dashboard and the user token was displayed. All of this was done in the sandbox environment. I added all the necessary keys in the app I am developing and I receive this message: "Error: Token does not exist. The token does not exist, the user must complete the Auth & Auth sign in process to generate token." What does it mean by "complete the Auth & Auth sign in process"? Is there an extra step I have to take for the sandbox user account after generating the token?
