I'm having a similar problem with Samsung Galaxy S7 v7 Nougat. After trying to sign in the app hangs with the circle going round. It cannot find what to stream with, or if I skip that it hangs or says reconnecting and then hangs. My TiVo v6 also has had a message in Network of C133. The V6 is wired to the router and shows no panel lights, so is connected. I have reinstalled the TV Anywhere app numerous times, have forced stop and also cleared the cache.
