There's an APK, T h o p T V, IDK if you know about it. The app uses JioTV and Airtel TV servers and streams Live TV from it. The UI is better for android TV's and there's no need of logging in via Jio ID or Airtel Number. I think the APK also has Ditto TV, But you won't need that because Ditto is plain garbage. As far as quality is concerned the highest that JioTV offers is 720p. You can select the quality of stream in ThopTV and for some reason the 720P on T H O P T V is better than High Quality on Official JioTV app.
The servers uses aliases like Jasmine for JIOTV, Aster for Airtel, and Daisy for Ditto TV
I won't link the APK but it can be directly downloaded (T H O P TV Website)/latest.apk
Also, If you want to watch live TV on your PC, google : "Airtel M3U8" and use the second link and use some player to play the m3u8 streams, Safari can play it out of the box
