Hi guys, I’m looking for Chromecast users and Youtube on Android (and iOS ?) to confirm this issue https://github.com/balloob/pychromecast/issues/255
Basically, when playing a Youtube video on a Chromecast, the state in HA is not updated. If you have seen this kind of notification “Watch on TV”, your help is appreciated and I invite you to read the issue above in order to at least confirm it on GitHub, then may be help troubleshoot as well
Thanks for your attention
