Question: Why is iMessage splitting group conversations into multiple threads after upgrading to iOS 8?

After upgrading to iOS 8 my group messages keep getting split up into different threads. Everybody in the threads have iPhones and before upgrading they were all working and sending/receiving iMessages just fine.

Now I'll have 2-3 threads with the same contacts (using their same phone numbers, not another contact point like iCloud email, Apple ID, etc.). My phone sometimes recognizes that the group is the same because it will automatically name the group the same thing, but other times it just puts the names of the people in the "To" line. In addition, some of the threads won't let me send iMessage so I have to reply in one thread and receive messages in the other (I send iMessages in thread A but the replies from the same people come back in thread B, but if I try and reply in thread B I can only send text messages even though all contact info is the same).

Update after OS X Yosemite: After upgrading to Yosemite, my Messages app on my MacBook Pro is now splitting the threads as well. It used to be that the computer understood the contacts were the same so all messages should be under one thread and just my phone was having this issue, but the upgrade changed that.

I have tried signing in and out of iMessage, upgrading to the latest iOS, turning on and off my phone, starting new groups, only replying to certain groups, etc. but nothing has worked.


iPhone 5s, iOS 8.0.2

Same problem here -- group messages are splitting into separate threads. There seems to be no pattern to the problem. Evidence:

(A) I have one thread w/ 5 people, all iPhones (all are iOS 8). Some of the group's texts arrive in the group thread, but some come in separately as if from an individual. If I reply to the "individual," some people see the reply but others do not. The rest of the group is having the same problem (with our group and with other groups). We've tried everything suggested here and in other discussions - signing out/in, resetting, deleting all threads and starting over, etc. But the problem keeps coming back.

(B) I have another thread w/ 3 people (two iPhones iOS 8.1, one Android) with similar problem. I can text to both people in the group thread but they each receive my text separately. If they text to the group thread, I receive theirs in separate threads.

This is getting ridiculous. Texting on iPhone is now worthless.

Good day all. There is actually a pretty easy fix for this, and the best news is, you don't have to delete groups, and you will not lose chat histories.

First, go to your messages list, and for each conversation that SHOULD be part of the original group, go to details, and remove any and all group names.

Reboot device or restart Messages

Go to each conversation and update its details to include all of the contacts which should be in it. Do this for every orphaned conversation fragment. *I found that I had to also send a test message to the modified group after I changed the participants.

Reboot device or restart messages

With the group names removed and the recipients updated, all of the fragments will consolidate when the Messages app restarts. If you still have some rogue bits, double check the steps a second time, and make sure the participants are correct. If problems persist after that, see advice above about making sure your contacts are correct, and that iMessage is using consistent contact information across devices.

Each participant will have to do this on their own device.

Looks to me that the root cause is related to group names. Like others, I did notice this around the same time as an IOS 8 update. Personally, I stopped caring after my groups were sorted out. I'm not getting paid to investigate bug fixes, I just wanted my groups to work again. I haven't tried adding names to the repaired chats yet, so idk if that will rebreak it.

Im having the same problem. This started with iOS 8 and Yosemite. Im in a group message with 10 people with and without iPhones. Currently have 9 threads and when ever a new person responds a new thread forms. they all have the same people but in a different order, that may be part of the reason why iMessage doesn't recognize them as the same conversation.

As I'm writing this post 3 new threads opened and other people with and without iPhones are mentioning the same problem

hope apple can fix this. VERY annoying

I am having the same problem also. Everyone appears to be on the New iOs most of the phones are 5's or 5s' I have the only 6. The newest issue was this weekend I sent a text to 2 members of the group text in a separate text. One of them received it in the group text and replied in the group text not the one with just the 3 of us.

I am having this issue also. Have an iPhone 6, MacBook, and iMac that are both running Yosemite. iPhone has 8.1. My brother also has an iPhone 6, and has no problem with the group conversations, even if we're in the same group text. His will show all the contacts in the group, while mine will only show 10. The only real difference we have between our setups, is that he has service through Verizon, and I'm on AT&T.

Following this thread, and hoping to get a fix soon.

if you're getting multiple messages it's likely they are sending from different devices, iPhone & iPad. Go under settings/imessage/send & receive and make sure all devices are set to start conversations from the same phone number (or email whichever you prefer) but all devices need to be the same to prevent multiple conversations when they use a different device. Seems to have fixed the problem for me.
