Have had an Arc since they released last year using the supplied hdmi cable etc, was running on my older Hisense N7 series was capable of turning the TV on and off using Alexa, however with my new 2021 Hisense U7G, I'm getting dumb problems everywhere.
I wiped Alexa from the Arc and deleted everything from the Alexa app, including removing anything from the desktop app at Alexa.amazon.com.
I've just run-through the process of setting up Alexa via the Sonos app, then had to download/enable the Sonos skill in the Alexa app. At the moment when asking to turn the TV off, she says "hmm, I can't seem to reach the lounge room TV. Try re enabling the Sonos skill from the app" etc etc.
Anyone have any advice? Hisense Australia were quick to palm off the problem and say it's not their fault at all, even though it was working perfectly fine prior.
Edit: I've successfully got Alexa to turn the TV on (!) but she just won't turn the TV off! You can see her attempt to, but the TV just doesn't want a bar of it. Any advice, people?
