I've noticed that after using the Music app on my ATV4 that the next time I open the app the launch process just seems to hang on a near white screen and the only way I can get back to playing music is if I force quit the app and then open it again. It then works fine until I quit the app and then some days later I try to open the app again and it does the same thing (freezes on launch). The Music app is the only one that shows this problem, none of the other apps have ever done this. Interestingly, there are reports of people having a very similar type of problem on iPhones running iOS 9.1 so I wonder whether this is an issue that is affecting all iOS products. Has anyone else noticed this on their ATV4?
