What happened to fading, iPhone 6s Plus

I love this app. Plan and simple, but I have recently upgraded my phone, and it appears that I am no longer able to fade the song selection in and out. I hope that this will be corrected/addressed along with the next update for this app. Such a great app to lose points on such a small but very significant option.
