automatic app updates not working since installing iOS 9.0.2
After updating to iOS 9 (and eventually iOS 9.0.2), apps are not updating on my iPhone 6, iPad Air 2 or iPad Air. In settings, I have them set up to automatically update. Does anyone have any suggestions about how to fix this. Tried shutting down devices and even doing a hard reboot. Reset my phone but no luck. I have to manually do the updates daily.
