I have an iPhone 7 (32GB) with iOS 10.3.3 and it seems like I'm not getting any notifications like "This App was updated" or "Some Updates are available" or any kind of Badges of available updates on App Store.
I have turned on All Notifications for App Store in Settings including Banners and Badges. I had my iPhone reset like 3-4 times (including Restore via iTunes) and it just didn't work. I have to manually go into the App Store every time and push it down to check for any available updates. Why can't it just happen automatically. I have seen updates badges on many other iPhones.
