iMessages aren't syncing between MacBook and iphone
I can send messages on both my MacBook (using macOS Sierra) and my iPhone 6 (iOS 10.2). The problem I'm running into is that I cannot see the messages I've sent from my MacBook on my iPhone and vice versa.
I've looked at my preferences and accounts on my MacBook and I only have the option to select my email (which is connected to my iMessage account) but I do not have the option to add my phone number - this is something that I've read as a solution on other questions.
I used to be able to see them both but for some reason it's changed and I cannot figure out how to fix it! Please help!
MacBook Pro with Retina display, iOS 10.2, iPhone 6 (iOS 10.2)
