This morning (11/26/2019) I and my wife started receiving duplicate text messages from everyone but my wife who happens to use message+ also. I followed the troubleshooting steps (issue number TR-481599384-TDC) but that didn't resolve this issue. I looked at the default messaging app and I'm receiving duplicate messages there also. Samsung Note 9. The last update was 11/9/2019 software version N960USQS3CJ1.
Edit: I believe this is related to group messages.
