I think there is a bug with the audio playback speed function. In a story, when you change the speed for playback it works fine, but if you swipe to another page or navigate to another story, when you tap to play the audio nothing happens. You have to reset the speed back to normal, then tap on the play icon. When you go into app settings and change the playback speed that way and then go to a story, it will not play. You have to set it to normal using the 3 vertical dots icon, then you can adjust the speed. It plays through the story fine at that speed, but it stops working completely if you swipe to another page or go to another story. This is on an Android phone. Using SAB 9.01.
