@TeamYouTube my Samsung TV YouTube app is not working from yesterday. It shows all the contents but when playing it is only giving loading animation followed by a black screen. Done reset YouTube app 4 times as well as the TV. But no use. TV model Samsung KU6470
It got fixed automatically on the next morning. Seems like a problem of YouTube codec. My TV does not support AV1 codec only VP9. YouTube changed the codec to AV1, that's why it did not play. But now YouTube has revert back to its VP 9 codec. Now everything is fine.
