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?
