Hi. I'm having trouble downloading an app for my iPhone 6s, saying I am in the wrong region. I live in the UK. It's the Horror Channel's Night Terrors app. https://www.horrorchannel.co.uk/NightTerror/ I've tried searching for an answer to no avail. It's advertised on a UK website but doesn't seem to install in the UK. Please help P.S i am a iphone virgin.
