T-Mo Nokia 5G21 Internet Gateway for Hulu or YouTube LIve TV Home Network

I have been using T-Mobile 5G Home Internet for almost three years, and I'm still using the original Nokia 5G21 gateway, with YouTubeTV. 

I can watch using the YouTubeTV app in my Samsung smart TV, as well as the YouTubeTV apps in my Roku Ultra and Apple TV 4K.  All work perfectly. Very occasionally, the changing IP addresses will require verifying my location.  The trick here is to verify location not through the TV app, but through your cell phone, which has a GPS and doesn't rely on the IP address to verify location.

 These steps are from the Google site, and they work for me:

On a smart TV

If you're watching with our TV app, you can update your current playback area (for example, if you're traveling).

1. Open the YouTube TV app on your TV.
2. Select your profile photo 
             >  Location
3. Select Update next to "Current playback area."
4. On your mobile device, go to tv.youtube.com/verify. Allow the website to access your device’s location to update your current playback area.

As my TV app and phone are both signed into the same YouTubeTV account, my TV app uses the location my cell phone just verified.
