The app has become painful to use

I don’t know what Amazon is doing, but the app has become very painful for me to use. It is slow and buggy. It delays before turning the page and some times skips forward too far. It goes crazy sometimes when I try to change the window size. I’ve been using it because it was available on more platforms. Now that iBooks is available on the Mac, I might need to switch.
