I started with iOS back with my 3GS, and it sits here beside me on iOS 5.1.1 with the typical red 1 on the settings icon. My iPhone 5 is upstairs on 7.1.2 with the same expected/"learn to live with it" notification. My 6S Plus, for whatever reason, only ever has this notification for a few days. I reinstalled 9.3.2 A few days ago since it was still being signed and the notification has again disappeared. I've googled this but the results I found were all from people asking how to get rid of the 1, is the ability to disappear new for iOS 9? I'm thinking it must be but I'm hoping to confirm. Thanks!
