I have been using the Beta App since the purchase of my tv and set up of my internet service back in July 2019. As of today is no longer works.
My TV is 2018 model number - UN65NU6900FXZA
The app now only works for:
2018 TVs with minimum software version T-KTSUAKUC and Model Code UNXXNU7090.
The goal post is always moved. Why the change? I can no longer stream TV.
contact set manufacturer as they may have a firmware update available or coming soon.
