I just noticed this odd behavior with the App Store on my iPad. In the past, whenever I made a purchased (free or paid) download, the App Store would quit automatically after I tapped on the install button, and the app would appear on my homescreen and begin the install process. Since earlier today, when I tap on the install button, the App Store will no longer quit automatically. The app will also NOT install automatically. Only when I MANUALLY close the App Store will the app install process begin. I have never seen this behavior before. Rebooting iPad was of no help. Help?
