I have bought a 55PFS7509/12, but most of the time the Spotify app is not working, not even starting. I have just got it to start twice in a month time...

When trying to start the Spotify app, sound from the selected source disappear, but nothing more is happening. I have tried to upgrade the software, but I have the latest release I'm told. I've also tried to restart the TV, but still without any luck.

Anyone else that has this problem? Can it be fixed?

Kind regards,
