I would give this app a 5 Star for being simplistic and fun to use. However, not long ago, my ps backbone just stopped working with the app. I thought it was the backbone, bluetooth a new controller (xbox), and even unistalled the app and reinstalled. Same issue, none of the buttons work except the R1 and R2. I tried unistalling the app again and using the 8Bitdo controller and same problem. Man, I really loved this app too.
