Bests & Worsts Reviews from Amazon

I've had this app on my phone, and have had no issues with it; however, when I download the Kindle version (twice), I've had to uninstall due to various problems. Pop-ups appear that don't go away unless I do a hard reboot, then reappear as soon as I open the app again. My system slows down, and my Fire doesn't perform well in general. This is a SERIOUSLY awful app!!
