Bests & Worsts Reviews from Amazon

I just got my Kindle Fire HDX and already had the Kindle Fire. I was looking forward to getting this app on my new Kindle HDX because my other Kindle didn't have enough space. This was the first app I got on my HDX but like the first reviewer, it just kept loading. Because of my love fore Toothless, I'm not giving up. Ever. Amazon please fix this!
