Apple TV app in LG OLED65B7P won't log in and is unresponsive

After installing the Apple TV+ app (v 1.0.2, 11/15/21) in my LG OLED65B7P and launching it, the app gets stuck on the "login screen" and won't initiate the login process. The TV is connected directly to my router via a CAT5 Ethernet cable so it is not a WiFi problem. If I manage to get the app to its "exit/cancel" screen, the app is also unresponsive. I have done a "hard reset" of the TV by unplugging it for more than 60 seconds and no joy. I also have removed and reinstalled the app without success.

This post is an effort to document this issue as the problem is centered on this version Apple's app. I state that because all other apps have no problem connecting to their vendors using the same hardware/Internet setup. Unless anyone out there has found a work-around, I guess I will have to wait for the app to be updated, if ever.

(N.B.: Apple TV works in two Roku sticks and in my ancient iPhone 5se. I had no need to access Apple TV in that TV until now and thought it would not be a problem. The best plans of mice and men and all that...)
