Missing volume icon since ios9 upgrade
my volume icon is gone when I reopen my iPad using my Smart Cover. To get it back I need to manually turn off and on using the side switch. I can manually raise and lower the volume using the switch toggle, but there is no icon that shows the volume being raised or lowered. If I don't close my iPad with the Smart Cover then I have no problem. Even when I close my Smart Cover, the clicking noise it is making is different from before ios9. I've tried restarting a few times and it fixes it until I close it with the Smart Cover then the problem reappears Again. I know it's not the Smart Cover as I've tried it on someone else's iPad and it works fine. Any advice would be helpful.
iPad, iOS 9
