iMessage splitting group conversations into multiple threads

I spent some time with Verizon and they did some trouble shooting and might be a coincidence but mine has stopped doing it. Apple is not correct. We are ALL having the problem since updating to Sonoma 14.6.1

I've been seeing the same thing, also just since 14.6.1. As it's only happening on the Mac, I have doubts about whether Verizon will have any idea what to do about it unless they've already been instructed on a solution by Apple.

I notice that on my outgoing messages to a group, only the people I'm sending to are shown as group members, as I'd expect. On the incoming messages, though, those people and myself are shown as group members. I suspect this difference in group membership has something to do with why the messages are split into separate incoming and outgoing threads.

Looks to me like a synchronization problem with macOS rather than a carrier related issue, unless Apple has provided details to the contrary.

I chatted with Apple today after realizing that this was only happening with non iPhone users being part of the group thread. Despite the common denominator of this happening after the Sonoma 14.6.1 update, their position is that this is carrier-related (I have Verizon). It seems very coincidental that this just started happening within the last week or so, but I am going to try Verizon. Are you all having the same issue ONLY with non-iPhone users?

Just to lend confirmation here - I too have this happening on conversations that have non-iphone devices texting and also have Verizon as my carrier. If this is a common thread I would love to know if you come up with a solution from Verizon, please.

Never been so "happy" to find a shared problem. Thought I was nuts. Yes, on all my devices (which are synched in iCloud) messages are split, a new group forms, and my name gets shown in the new group. I THINK this is only happening when an Android member is in group - not sure. And yes, my Macbook is 14.6.1, and my iPhone and iPad are updated --and of course it's happening on all due to synching (which had worked right for years...). QUESTION: how do we determine if/when Apple addresses this and prescribes a fix? I am not a tech whiz but can do what I'm told, to fix! THANKS

Maybe Verizon was the culprit in this. Mine has returned back to normal mixed-OS threading for the last 5-6 days. Does anyone else see the problem resolved or are you still having it? It seems that everyone with the issue was with Verizon, so I am hoping this is resolved.

Ditto! iPhone 14 pro Max and this started after I updated to Sonoma 14.6.1. Only on my Macbook, not my phone. Following ... hoping Apple will pipe in here.

After posting Aug 30, reading more, and making sure that yes, this is only happening when there is Android(s) in the group, I spent an hour on phone with Apple Aug 31. They found no solutions and told me to call my carrier, Verizon--which I will do after this holiday weekend. I think that will be a waste of time. Maybe if enough of us bother Verizon they'll bother Apple...The tech seemed to find it particularly interesting that when the messages split off into new group, the new group now includes my name as a member--which I've seen others mention. I know this post doesn't add much... just wondering if enough of us Verizon folks call, that might get them to be sick of it and work with Apple. Or not.

Thanks for the hard work. Telephone support can be a pain to get through. All is working well for me this morning. We will see if it lasts. We are on Spectrum Verizon so it could be a Verizon problem.

Having the same issue on my iPad. I have an iPhone 8 which hasn’t be affected but it’s very frustrating having my texts coming in in different threads with my name now added to it! And, it only seems to be an issue when there is an Android user in the group. Hope Apple or Verizon fix this soone. It’s making it very difficult to keep tract of conversations for work.

Just got around to doing my update to Sonoma 14.6.1 this morning, immediately noticed all group chats with at least 1 android user are breaking apart now and it is reflecting on my iPhone as well. My only solution at this point is to reply to android containing group chats on my iPhone only until Apple gets off their butt and fixes this.

I'm a T-Mobile customer; just switched back to iPhone and my group text includes only other iPhone users. Randomly, a reply from another person in the group will start a separate group iMessage thread. It's not the same person's phone initiating the issue. I do have iMessage on my MacBook Pro, but I'm not sure I've ever actually used it to message in this group text.

I'm also experiencing the same issue. Started several weeks ago.
