Message from a individual contact being received as a Group Chat on my iPhone
Randomly, I began receiving group chats from a single contact. For example, contact sends me a message and it arrives as a group chat from that contact, but separated into their email and phone number as if it's a group chat including myself and them from 2 different contact sources (email and phone number). There profile picture shows up on both the sources, showing they are from the same contact info. I didn't change anything on my end nor did they on theirs. We did both get new iPhones and a switch in carriers, don't know how or why that would affect this.
