Bug description

If I create a group thread and add non Signal users and send a message to the group all of the replies come in as a new thread and not in the existing thread that I created. It appears that I am not added to the list of members when I look at the group members for the thread.

Steps to reproduce

Open Signal create group thread send message when recipients reply messages show up in a new thread.

**Actual result: Not added as a Group Member to threads I created
**Expected result: All Replies should show up in the existing thread I created

Screenshots

Device info

**Device:Pixel XL
**Android version:8.0
**Signal version:4.11.5

Related to #7091? In this case 4.12.x will fix this issue.

Not exactly the same issue I never created a separate thread and the message order is the same. It is the same issue as @wesdawg mentioned on that thread however.

I enrolled in the beta to receive the current version which is 4.12.2. Now half of the replies I sent have been added to the new thread that was created and all of the other messages are in one thread by themselves with no other messages.

I have deleted all of my group messaging threads which is a pain because they are not backed up by the export option. I will test and see if the issue is still on going after I recreate my group threads but it looks like it is not resolved entirely.

I wonder if it is related to the fact that Signal is not displaying my contacts phone numbers correctly. I have all of my contacts phone numbers stored in the format of Country code + Area Code + Phone Number. All with the hyphen between the phone number and area code but Signal displays some correctly and others without the hyphen.

I have this issue too. I've noticed this common occurrence:

1. I text some of my family (they have iPhones w/o Signal at the moment)
2. They text me back
3. It comes in a group message with them and another number (mine w/the country code). Rather than saying "Me" in the list, it says "+1MYNUMBER" instead. Seems like Signal needs to recognize MYNUMBER as the same thing as +1MYNUMBER

Still not resolved in 4.12.3. I created a new thread and the message replies when I got them came back in a new thread. If this was in Broadcast mode this behavior would be expected but not in conversation mode. Updated Bug Report Below.

I am also having this problem on my Google Pixel.
Android 8.0.0.
Signal 4.12.3

Let me know if I can provide any more information to help with debugging this issue.

@ONUHWT @KatamariSanChan typically the devs ask that we don't add "me too" comments to the issues unless we have new information or a log file or something like that to add. If you want to "me too" something, you can add the reaction (thumbs up/down, smile/frown, etc). Otherwise this emails hundreds of people.
