Xfinity App not working

I get App Temporarily Unavailable and "Cardio is currently unavailable (V301).



Then directs me to http://tivo.com/support/V301 which leads to nowhere.



Found earlier threads but it seems the problem corrected itself?

Though I found this as well:

Anyone encounter this recently?
