Greetings, Rgibsona! I appreciate you taking the time to reach out to us here on the forums. I hope you are having an amazing day. I apologize to hear that the Sundance Now currently does not have the option to authorize your subscription through their app or website at this time. It's possible this may become available later on down the road. Looking into what providers can be authenticated at this time it looks like they are only set up for two. I apologize for the inconvenience.
