It's been happening since the last week. I put events into my iphone and sometime later when presumably it syncs with mm online, the event disappears. Everything use to work perfectly - no settings changed so i'm at a loss! Is anyone having this problem? It's bloody frustrating..if you put something important in your calendar, we should as users know that it's there and it's not going to disappear! MM has been out for a while now so i would have hoped they would have sorted out this mess. Never had a problem till now.
