I've just purchased and set up my new Galaxy S9. Seems to have mostly gone smoothly however found I'm unable to configure my ringtone or notification sound. In settings they are set to over the horizon and skyline respectively. However when I select either menu option, no system sounds appear, just 3 audio files, 2 of which I think came from using smart switch. When I try to select one of these files, I get an error "unable to set as ringtone". Anybody any ideas??
