I just started having the same problem with the WatchTCM app yesterday. The app was working fine on my iPad (new in 2018), with my provider, Spectrum. Now, it’s nothing but problems. I have deleted and downloaded the app several times, several different ways. (And I’m at home, using our own secure network.) The app downloads, prompts for the cable provider, I select Spectrum, and . . . nothing. Nothing but trouble. Ironically, the app continues to work fine on my iPhone.
