iOS iMessage force sync
My iPhone X randomly deleted HUGE iMessage conversations dating back to the beginning of time. These were close friends and family, and while not critical, I'd like to have them back.
These conversations EXIST on my iPad mini 2!
How can I force iMessage on my phone to sync with the full conversations that exist on my iPad?
iPhone X, iOS 12.0.1, And iPad mini 2 up to date
