Calendar invitations not working
Have a strange problem. My wife and I use both iPhones and iPads. When she sends me a calendar invitation, it shows up in my calendar app, I accept it and no problem. If I send a calendar invitation to my wife by typing her name in the invite space, it comes to her email. If she selects “accept” it immediately goes to the iCloud in Safari showing it was accepted. But it does not show up on either her iPad or iPhone calendar. Then if I put her phone number in the invite space, it comes up with her name (and a question mark) and then I send her that invitation. It then shows up in the calendar app to be accepted, but does not show up in the iPad calendar, and shows up twice on the IPhone calendar. I have made sure that we are both using the iCloud calendars, and to the best of my knowledge our settings are the same. Any help?
