I'm on an iPad Air 2. Trying to download an app but the app sorta in limbo. Won't open when I click on it and it won't delete when I try to delete it. I think it's completely downloaded. When I go to the purchased tab on the iPad, I see the app and I try to open it but nothing happens. I've restarted the iPad, I've done the power /home button, logged off/in out of iTunes, but nothing seems to work. I tried and was still able to d/l more apps no problem. It's just the one app and I'm stuck. Help??
