No problems except it required me to add two extremely annoying security questions. It's annoying because it's just a stupid app and the screen cut off half the words in the questions and typing the answers on a cell phone and ensuring it's totally correct (and that autocorrect doesn't change it) when you need it to be the same thing next time, is aggravating.
I was surprised it was compatible even with my ancient LG Optimus M which runs Android 2.2.2
Mine hangs at the point where I put in the two security questions and hit "next". I'm gonna wait for the first update and see if it works any better after that. Till then, everything that doesn't require me to be signed in, works great.
