Smart things no longer finds My Samsung TV

Hi all.
Smart things would always turn my TV off and once in a blue moon switch it on…today Alexa kept saying there’s a few devices with that name and won’t even turn it off, so I decided to delete the app, remove the tv from the Alexa app and start again.
Smart things will not now find my TV but in th Alexa app it will but says the skill using it is smart things , it sused to come up TV series 6 , they are in the same WiFi network ! Any ideas ?

Others have been seeing Alexa issues today…

Are you using STSC to connect your TV?

Sorry STSC ? I’m using the app on an iPhone , worked previously , other things find the TV on the network
