[iMore Question]

When I went to add an appointment, a banner covered the screen. It talked about an update that would show reservation times, traffic time to be added, etc. I pushed
' continue ' (the only option available). Now when I push on a date to add or edit an appointment already entered, it will not open. I cannot add new appointments. It has stopped responding.

Double tap on the home button to revealed the app switcher. Swipe up on the Calendar app to remove it from the list. Now reboot your device. That *should* fix the problem for you.
