The conversation thread with my wife shows up as a group mms on my phone but as a regular individual thread on her phone (we both are using Message+ on the Galaxy S7 Edge). On my phone, he bar at the top of the screen -- the recipient bar -- with the participants in the group shows: <my phone number>, <wife's name>. However, on my wife's phone, the thread shows up like normal, i.e., it only has my name in the recipient bar and is not a group MMS.
This also doesn't happen with everyone I'm texting with...only my wife and one other person.
This has been happening for the past few months. I'm using Message+ version 6.4.39.
Help!
Thanks,
David
