Calendar time to leave alerts not appearing consistently
Is anyone else having issues with time to leave alerts in iOS 9? When me or my wife add entries to the family calendar sometimes we both get the time to leave alert and sometimes only one of us gets the alert. Also we both have an iPhone and iPad each (I have an iPhone 6 and iPad mini 2 and she has iPhone 5 and iPad 4), sometimes the alert appears on one device but not the other. It seems very inconsistent.
It somehow looks as though it only works for the person who created the alert even though we put the calendar entry in the family calendar.
