I have a Samsung Smart TV UE49KS7000 with the spotify app pre-installed.  For over a month I have been unable to access Spotify on my TV- when I select the app, I am greeted with a black screen only.

The app is fully updated and I am unable to uninstall and re-install as the app is pre-loaded on the TV.   The TV's software is also fully up-to-date.

Any ideas? Thanks
