Smart TV App stalls

On our LG Smart TV I am able to select AppleTV+. Main screen appears. After selecting Series or movie to continue a wait star (circle) appears and nothing happens. After several minutes of nothing happening, I Exit. And try agaon and again with same results. Went to Account settings and RESET app. Still have same issue, but it begins on sign in. Selecting sign in results in wait star (circle) and nothing happens.

I am able to sign in on my iPhone and my laptop and all works, Failure is only on LG Smart TV which worked fine until yesterday.
