How to retrieve lost group messages on iPhone from another member's device?
I am a member of a four-member group on Messages. All of the messages within that group have disappeared from my iphone and the iphones of two of the other members. The messages still show up on the iphone of the fourth member of the group. How can she save all of those messages so that the rest of us can access them?
