We're no longer supporting the Viki app on Samsung Smart TV. As Samsung announced they will no longer be supporting apps made via Smart Hub on Samsung Smart TV devices, it'll be hard for us to continue supporting this app.
We hope to bring you more and better apps in the future on Smart TV devices.
There are many ways you can watch Viki! You can check out all our available apps here.
If you have any questions regarding this or any other issue, feel free to write to our Community Experience team here.
