Hi, I've just found out that my phone is not sending invites to my wife's iPhone from my calendar entries. I'm not sure whether this is a result of iOS 10 or that I have upgraded from the iPhone 6 to 7. I enter the event as per usual, add my wife as an invite but my wife doesn't receive anything. When I've gone back an checked my entry she still shows as an invitee but says no response. Can anyone help please? Cheers.
