AI agents (likely to be Meta AI) can access WhatsApp group and individual chats and contact details unless the Advanced Chat Privacy feature is enabled.

Original review summary

The review says Meta AI can access messages that mention @Meta AI or are intentionally shared with it, but cannot access entire group chats or members’ contact details. It also says Advanced Chat Privacy does not control Meta AI’s access, which is already limited, and that personal and group messages remain end-to-end encrypted.[S1]
