I thought that the Airpods were supposed to automatically connect depending on which Apple device you are using. So, if I'm using an iPad Pro and pause my show and then want to listen on my iPhone 7 Plus, I thought it would switch automatically. However, I haven't gotten it to do that. Am I doing something wrong, or does switching require manual intervention. If it does, then I'm returning these and going back to my old headphones which connect to two devices simulataneously and automatically switch. Thoughts?
