Shared Reminders work in one direction only
I'm the owner of a list which is shared with my wife. My wife can see the list and she can see new items I add to the list over time. However, when she adds items to the list, I don't see them. If she marks an item as complete, it doesn't disappear from my side.
We've deleted the list and created brand new one but that didn't fix the issue. We've tried un-sharing and re-sharing but the problem persists. Does anybody know how to get these working again?
We are using the current versions of iOS and macOS.
