About message history on linked devices
Right after you link a device, your primary phone sends an end-to-end encrypted copy of your most recent message history to your newly linked device, where it’s stored locally. Learn more about end-to-end encryption in this article.
Note: Not all messages are synced to WhatsApp Web or Desktop. To see or search your full message history, check your phone.
