App won't work – SiriusXM: Music, Sports & News Review

I can't get this app to work. I love listening to XM in my car and I want it in my phone, but this app is terrible. It keeps saying ((loading)). I have a really strong wifi, so I don't know what the problem is. Channels aren't up to date either.
