With Roku and Google still unable to reach an agreement regarding YouTube TV's distribution, Roku has pulled the YouTube TV from its channel store. The existing deal has lapsed, and so Roku couldn't have the app on its devices anymore. But according to the company, it is "taking the extra step to continue to offer existing subscribers access to YouTube TV on the Roku platform unless Google takes actions that require the full removal of the channel." Any new subscriptions from the YouTube app are also switched off "until an agreement is reached."
Roku warns its customers in an email that the YouTube TV subscribers or those who have the app on their Roku devices shouldn't delete them as they won't be able to download it at the moment. The main YouTube app isn't affected by this change.
