@siracusa I just listened to the last two episodes of ATP and I might have a fix for your iMessage group thing. I have experienced this many time and the only thing that has consistently worked for me is to remove all customizations to the groups, name, profile photo, background, everything. Bring both groups down to standard groups with no customization force quit iMessage and give it a few minutes. When you go back into iMessage, the groups should be merged.
