In the very few days I've owned my Lumia 928, I have been enjoying the MixRadio app very much. But then this morning I was having some trouble, getting a message of "We can't get through". I thought I'd visit the website to see if it was just a phone thing...turns out it probably isn't. Has this happened before and if so, how often? (http://www.mixrad.io/us/en is the site I'm visiting on my computer)
