Prompted to complete setup for Channels DVR

New to Channels DVR. Using Apple TV 4. Each time I turn on my TV and open Channels app and click on the DVR heading I receive a notice to complete my setup of the DVR at a given URL. Will this eventually stop or what do I need to do to complete the setup?

Did you maybe install the DVR on two different computers? What does it show when you visit the url it says to go to?
