I'm very sorry to hear that has happened. In order for me to help you most accurately, please provide the complete model code for this device.
Previously this app has worked on my Smart TV. Recently I keep getting a message saying there is a "Network error. Please try again or quit the application (undefined)"
I select "Retry" and it doesn't do anything. The only way I can quit the application is turn the TV off.
This app installed in a Smarthub update so I can;t even locate it as a listed App to reinstall it to see if that would work.
Any help is appreciated. Thank you!
