Xfinity Stream app is designed not to work on my brand new LG smart TV

Perhaps this will be useful for others who try to use the Xfinity Stream app. It turns out the app does not work on most TV installations. 

Xfinity Stream fails to work on my brand new LG TV. I installed the app, signed in, and it returned the error message "This package is not yet available on this device." "TVAPP-00195"

I contacted Xfinity support and spent several hours over three days trying to get help. I chatted first with the Xfinity AI assistant.

Then I was directed to chat sessions and phone conversations with Xfinity staff in Bangalore, Delhi, the Philippines, and an unspecified city in northern India. 

The problem was finally resolved by an Xfinity technician in Mumbai. He told me the Xfinity Stream app will not work when the TV is connected to the Internet with Ethernet or with a home WiFi network. The app works only if you use an Xfinity WiFi network.

Thus, the app is designed not to work with most Internet connected TVs including mine.

The question that arises is this: 

Why when I reported the error message did the Xfinity support staff not immediately ask me about my TV network connection? 

Why are they not trained properly to resolve this very simple error with Xfinity Stream?

All of the Xfinity representatives were very pleasant, very helpful, very patient, and followed the script that didn't produce an answer to my question. I rate them all as 10. Great people. I had fun chatting with them half a world away. A half dozen times with each Xfinity representative I was directed to delete the Xfinity Stream app and then download a fresh copy and install it again. Each time we got the same result, the same error message, as expected, of course.

During the process one of the Xfinity reps did something to my Xfinity Gateway modem and I lost my home phone service for two days. It took an hour on my cell phone with the rep in Mumbai to get phone service restored.

One of the reps told me there was a problem with my comcast cable line. He arranged a home service call for two days in the future. I then got phone calls from other Xfinity reps telling me there was nothing wrong with my cable connection, so they canceled the service call they had scheduled.

At the end of three days, some 7 hours online and on my cell phone, multiple logins and reinstallations, I finally got the answer that the Xfinity Stream app will not work on my LG TV.

I have Xfinity because when I moved to this neighborhood it was the only ISP available. The service has been generally good so I stayed with Xfinity. But Verizon installed FIOS fiber optic cable a couple of years ago. As I write this another company is installing a second fiber optic network in the neighborhood. Comcast no longer has a monopoly in my neighborhood and it's supposed benefits don't even work. Time to look at those alternatives as Comcast falls further and further behind its competition.
