Hello, ive got LG 55UF7787-ZD and i dont have available Spotify on it. I tried everything, even upgrade firmware by hand, but nothing helped to get it available for me. If somebody has some solution how to install an app to the TV, please let me know. I am not interested of some tricky crazy converting of albums and downloading it in advance. I am really looking for solution to have installed application in my TV, thank you.
