Hey @TeamYouTube why isn't there a way to turn off the TV connection for youtube? Its incredibly irritating when you accidentally hit your phone and it begins playing youtube on a device it was never connected to. If there is any way to disconnect it please let me know.
Thanks for trying all those steps. Please send a feedback report directly from YouTube with these steps: https://goo.gl/WdI0BK . While every individual report may not get a direct response, we do review everything and use the details to investigate and fix issues.
