Messages on Mac displaying “Not Delivered” but message is being delivered
I've tried logging out and back into my Apple ID account on my Mac, but some (not all) messages are showing the red exclamation point and "Not Delivered", but when I go to the same thread on my phone the message shows up as delivered. I've also checked some of them with one of the people I was chatting with and they are being delivered.
