Same group, multiple group chats - How to fix? I'm in a group chat with 3 others. We all have iPhones. About a month ago, a new group chat was created with the same group. I deleted it, but it came back. 3 of the 4 of us experience this problem. The other guy has no idea what we're talking about when we say "this is driving me crazy."

Many others seem to have also experienced this problem:

There is no answer in the above thread.

How can we fix this issue?
Make sure "group messaging" is turned on in settings.  For some reason (maybe b/c i have hard and soft rebooted my phone a bunch) that option switched off.
