Dear @Phillip Taylor ,
Thanks for posting your issue on Q&A Forum. I understand how challenging this situation can be, especially when group chats are a vital communication tool. Based on what you've shared, instead of replying in the original conversation, it creates a new group chat with the same members. Unfortunately, this results in not just duplicate chats for you, but also duplicates on your friends’ and colleagues’ devices, further muddying the conversation and status updates.
Following my testing and research, below suggestions may help you address this issue:
- Update and Patch: Confirm that your Windows PC has the latest Windows updates and that the Phone Link app is current. Likewise, verify your Android device is running the latest available OS update.

Please note that resetting may require you to reconfigure your linked devices.
- Unlink and Reconnect Your Device: After the reset process, open the Phone Link app on your Windows PC and remove your existing device link. Then, go through the linking process again to reconnect your Android device.
- Review Your Messaging Settings on Android: Double-check your messaging app settings on your Android phone to ensure group messages are correctly handled. For instance, some messaging apps might need to be set to send messages as MMS (or the platform’s recommended format) for group chats to be recognized correctly across devices.
