LG 49UF772V + Spotify

[imser]

I recently bought this TV and when it was installed I connected it to the internet and logged in at my Spotify account, since the TV have the app. Everything worked just great, I could listen to all music all day long.

But now, a few days later, I can´t get it to work. When I open the Spotify app, it says "There is no active user on this device. Please select an account below or add one." I click on my user account but nothing happens. It just stands there, ticking and trying to log in.

Is there any way I can remove my account from the TV and then add it again?
