PS4 PlayStation Music App with Spotify - How to re-set the TV dimensions?

[Tyridan]

Hi,

I had already registered my Spotify account with my Playstaion Network account on my PS3.

I just got a new PS4 - I downloaded the Spotify App and opened it.

The first thing it asked was for me to adjust the TV dimensions to maximise screen usage - somehow I fumbled the controller and clicked accept. Now I can't seem to re-do this step.

I have tried deleting and re-installing the app twice, but the settings must have been saved into my profile. Any idea how to hard reset the app, or remove the screen dimensions from my profile so I can perform this step again?

Thanks,

Michael Taylor
