I'm having an issue on my Verizon GNote 2 with the Amazon MP3 app. I can't sign in to it. Whenever I click the sign in button, a small popup flashes really quick on the screen saying "registering this device" and it doesn't do anything. It flashes so quick, I had to keep hitting sign in multiple times just to see what the popup was saying. I never had this issue on any of my other phones. I spent 30 min on the phone with amazon support last night and they are supposed to research it and get back with me in a week. Anyone else having this issue?
