1. No notification badges on "Frequently used apps" card in Feed (though they do appear in the App Drawer 2. Impossible to open hidden dock from the bar (using traditional Button Nav layout)
3. Some gestures don't work - most importantly to me: Tap Home Button in Homescreen (to open camera)
4. Launcher does not re-appear on main screen when returning from an app using the dual-screen accessory of my V60. Bing Daily wallpaper appears, but no launcher pages appear requiring re-start of phone.
