You might get more responses by providing details. And just out of curiosity, how is this an iOS 12 issue when a 492-day old message couldn’t haven’t been sent with anything newer than iOS 10.
This is old problem and sometimes happens after reboot and so on on iOS 10, iOS 11 as well. Maybe even older iOSes...
Yeah...I've had this happen on occasion after a beta update throughout iOS11...always clears itself up after a hard restart
