Use this apk USTVGO 247. It is exactly the same as USTVGO.
This app I have installed on my Shield Pro, Shield Tube, Fire HD 10 Tablet, and my Samsung S8 phone.
It works fantastic on my tablet and phone without any issues. On my Shields it plays just as well as my tablet and phone, but it requires the use of a mouse to better navigate around the app. I used Mouse Toggle to remedy that issue, and it worked great until the Android 11\Nvidia update broke it. So now I use my SHIELD TV PHONE remote until a fix is found. If you do not use Nvidia’s then 5he Mouse Toggle app should work fine.
Although, you can make a shortcut for a website stream. This is a much better solution.
If you are looking to do a shortcut for a website on your computer that very simple and I can show that process, also.
