For me, it's not just iOS9. I am running iOS 8.4.1 [12H321] on my iPhone 6, and JRemote 3.10. All worked well until yesterday [20150825] evening. I played hours of music through JRemote, and then last night, it just stopped. It briefly starts up, shows a "Connecting" screen and then quits. I even wiped it off and the phone and started with a fresh install. Same problem. Interestingly, the identical configuration on my iPad mini continues to work fine.
