Since my iPad upgraded itself to iOS 12.2, my iPad, Mac, and iPhone are no longer in sync in Messages. In fact, every one of the messages that I participated in yesterday are gone. Poof! Not only is this inconvenient, but it keeps me from trusting the integrity of any of my messages. Has Apple decided to throw out the text syncing? Or have they broken it again? I am not asking for much: I just want it to work the way it used to. Is that possible?
