My wife and I just got new MacBooks and in setting up the Messages app I've run into a problem with the phone number selected in the Message preferences. We share an iCloud account so we can share calendars, contacts, etc. and in the past have had no problem using Messages on our laptops by just selecting the correct phone number in settings. I've set that up correctly (I think) with her phone number selected and mine greyed out but she continues to get texts sent to me and doesn't receive texts sent to her. I've logged out and back in but that didn't do anything, though now she gets notifications about messages sent to her - though when you go to the messages app all that is there are my messages. I ran into similar problems a few years ago when I was setting this up and I eventually found a fix but I can't remember exactly what that was. Any help will be appreciated.
