Try restarting your iPad. Press and hold both the power and home buttons until the Apple logo appears, then release both buttons and wait for the iPad to restart. Then open the App Store to see if the incomplete download is gone.I have an app that appeared on my home screen. When I try to open it, it just shows it is waiting and nothing happens. When I try to delete it nothing happens. Any help or suggestions would be appreciated.
I would do the update to 9.0.2 and hope for the best. I can tell you that 9.0.2 is good on my mini. I'm happy with 9.0.2 No big problems yet. Good luck!
Did you try restarting your iPhone after turning off passcode lock?
