Just bought our Hisense R43A7200UK SMT ROKU TV this week and so far very pleased with everything.
However, having successfully paired Alexa with the Roku and having most things work okay, it does not seem able to change the viewing channel on Live TV. The spoken request is made to Alexa but the TV just shows, "Sorry something went wrong, please try again" - trying again doesn't make it work.
Any advice would be greatly appreciated.
We have the same problem in a UK TCL Roku TV. Did you find a solution please?
No I'm afraid not, Alexa can switch the Roku off but little else. 😞
