Question: The application “Calendar.app” is not open anymore.
I had just put in several new calendar entries. Then I closed the app. When I tried to open it again it kept bouncing. I tried to force close it, but it just sits there the Force Close is still available.
I found it in finder and when I open the app I get the pop up: The application “Calendar.app” is not open anymore.
I also have the app on my iPhone 7 as well as my iPad. They are still working.
