According to the latest information, Google Messages to auto-group SMS texts and RCS chats seem now disappearing for some users. The issue was first reported by 9To5Google, as per the source, the disappearance of the All, Personal, and Business category chips underneath the search bar as if the feature was not enabled.
Here’s how to check it, just go to Settings > Message organization, the “View messages by category” toggle and ability to select the “Primary category view” are gone, though “Auto-delete OTPs after 24 hrs” remains present.
The Pixel smartphone maker has confirmed that these features will be the first rollout to English users around the world. Meanwhile, this disappearance of categories in Google Messages is not impacting all users.
