Strongly suspect this has broken smartthings integration. Have no idea when this was pushed to my tv as it is on auto update but for the last week or two I have not been able to connect to smartthings or control the tv with Alexa for my RU7020. Even thought the tv is connected just fine to my network and all apps work ok. The app and the Alexa skill though complain that the tv is offline. No amount of signing out and then back in to my Samsung account is bringing that functionality back.
remove tv from Smart things than add again to smart things. connect tv to network through wifi and remove any wired connection. I faced the same issue after this they were resolved
I actually signed up just to comment that -at least for me-, some h265 rips I have now actually play Dolby Atmos to my soundbar. Earlier firmwares would play no sound at all and display a message of wrong audio format. I had to re-encode with DD 5.1 to get it to play. Quite a big deal if you ask me.
