Is the refresh token supposed to change upon using? I've combed through some similar questions and haven't found any real answers. I know the reason for changing is that someone would be using the access token instead of the refresh token. But I assure you I am using the refresh token.    I am looking to have a simple email signup on my site and having to manually go in and update the access token is quite unrealistic. I have it so that every time someone signs up, the refresh token function will be fired and get a new access token. Upon testing, each time that function is fired, the refresh token changes and cannot be used again. Rate limiting is not going to be an issue in this case. Any assistance would be helpful. Thank you. ... View more
