iMessage conversation history missing?
After the latest update, the conversation history disappeared for just one of my contacts (as far as I can tell). It only goes back about two weeks. If I have them interact (like a comment or pic) then it starts to download more message history... about a week's worth at a time, but I'm missing years and years worth of messages! Also it doesn't seem to be a permanent fix, as I just checked again and I've already lost some of the messages that I thought I had gained back. Soooooo frustrating! Doing a restore from back up won't fix anything if it won't download them from the cloud where they're already stored... correct?
