I'm having a bit of a strange issue. I was messaging someone (through iMessage) on my iPhone, and as soon as I got home, I opened it up on my Mac, and realized I couldn't see any of his replies, so clearly the messages didn't sync to my Mac. I tried signing out of Messages and in again, which did nothing. I also tried disabling and re-enabling my Mac under Messages > Settings > iMessage > Enable Messages in iCloud (I unchecked and rechecked this), and I still can't see any of his replies. I also tried restarting, which didn't work. What's weird is that I can see all the messages I sent to him, but not any of his responses. Any ideas as to what's going on?
