Google Confirms Bug That Splits Group Chats in Messages

Overview

• Users report Google Messages is creating new group threads with the same participants but without prior message history, fragmenting ongoing conversations.
• The problem has left people frustrated because replies can spawn multiple separate threads and past messages are no longer visible in the new threads.
• Reports come from a range of phone models and many users who recently switched devices, suggesting device migration or account metadata may be a trigger.
• Google has acknowledged the issue, told users it is investigating, and instructed affected people to open Messages and send feedback with the tag #splittingthreads.
• There is no reliable workaround yet and some third-party links like Messages for Web or Phone Link may merge threads visually even though the app treats them as separate conversations.
