YouTube TV is finally coming back to Roku after after a prolonged dispute

The dispute between the two parties that has dragged on since April of this year has finally been solved. If the feud hadn't been settled, the main YouTube app and YouTube TV could have disappeared.
A person with the company said that they had agreed to a multi-year extension for both YouTube and TV. The agreement will make both YouTube and YouTube TV available for all streamers on the Roku platform.

The company pulled the service because of anti-competitive demands made by the company. It was retorted that Roku's claims were "baseless" and that it was focused on "ensuring a high quality and consistent experience for viewers."
If a deal wasn't reached by December 9th, the main YouTube app could also disappear from the Roku devices, which would have been felt more acutely by the owners. Extra clarity to the negotiations may have been brought by that negative press. The YouTube app is safe now that the contract has been resolved, and you should see it on your device soon.
