I just swapped my iPhone 6s for a 6s Plus and completed its restore from the backup. Since I'd been using the 6s, I know which apps have 3D Touch capabilities already, but I've now noticed something odd. A few apps on this iPhone no longer have the home screen shortcuts pop up when their icon is pressed hard, however, inside the app, whatever 3D Touch abilities it had, do still function. Some of the apps doing this are Instagram, iTunes Store, App Store, Music, PCalc, and Twitter. As I said, inside the apps, 3D Touch works, but the home screen icon doesn't give the pop up short-cuts when pressed hard. Other apps with 3D Touch are working fine. I'm on iOS 9.0.2, I've tried a hard reset, and I've deleted and reinstalled the apps. The iTunes Store App Store, and the Music app obviously can't be deleted, which makes this bug seem even more pervasive. I've also tried turning off and on the 3D Touch feature in Settings. It took forever to restore and setup the phone from back up, so I'd prefer not try erasing it and reinstalling everything. Any suggestions? Anyone else experience anything similar? Thx for your input.
