Biggest Current iOS Gripe 

The barrage of notifications for calendar invites that you’ve seen and dealt with on other devices when you unlock your phone for the first time in a while is so horribly annoying. It’s caused me to inadvertently decline invites when I’m trying to swipe the notification away.

The calendar knows I accepted the invite. Why is it giving me this blast of prompts? I think this started in iOS 10, but I hate it.
