TV is advertised as Alexa being able to turn off and on, control volume, change channel and search on YouTube.
I can only seem to turn off and on, anything else it says 'TV doesn't support that'
I have just purchased the RU7100 and i am having the same issue as the original poster. The Alexa will switch the TV on and off but when you ask to do anything else it says that ' TV doesn't support that ' ????
