I can't get calendar.app from the iOS app store I can't download / get calendar app from the iOS app store. I just updated to iOS10 and when I finished I noticed that something was missing in my home screen. I took me a while to realize that I lost my calendar app. 

When I tried to get it from the app store I just couldn't. I can push the "get" button that transform into a install button. When I tried to push install I just can't. I can get any other apps from the app store. Buy or just get it. 

Is this a normal behavior? 

Thanks!
Try to restart your device whit:


On an iPhone 7 or iPhone 7 Plus: Press and hold both the Sleep/Wake and Volume Down buttons for at least ten seconds, until you see the Apple logo.
On an iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until you see the Apple logo.


If the problem persists, make sure you make all system updates.

Try an alternative to load a Backup of your device from iTunes to restore the calendar App.
