I know this has been an ongoing question/debate on the best way to make this work, but can any iOS 11 Beta users shed some light on muting notifications while streaming music? Did Apple happen to address this and make it easier to accomplish? It's quite annoying listening to the music volume fluctuate while streaming Amazon Music through Bluetooth in my SUV. I know I can use the mute switch, but I am hoping something may have changed in iOS 11. Thanks!
