iOS Calendar issues

I have a shared calendar with my wife it’s no longer syncing when she adds something, but if I add something it’s on the calendar. Also I was looking through her calendar trying to figure this out and I noticed she has 2 family calendars and other calendar titles I asked her and she has no idea how they got there she thought I did it.why does that happen? If neither of us added anything. And one more thing is that if she adds an event it shows on her calendar for family and her personal calendar, any ideas why that happens and how to stop that? I never had this many problems with my calendar, not sure what she is doing.


I’ve had the same issue between myself and my wife. Events will show up for between the two devices for awhile but ultimately they stop for no reason. I’ve gone as far as deletes and the shared calendars and making new ones but the same problem existed.
