WhatsApp has gained a new update that pushes its multi-device capability to the stable version after a few months of limited availability, allowing you to sign in to multiple devices at the same time and send messages even without your phone.
The feature’s expanded availability was discovered by WABetaInfo, which also noted that the option to opt-out of the multi-device beta program was removed in the app’s most recent beta update (v184.108.40.206). Installing the new update prevents those who participated in the beta program from exiting the program at this time.
If you are enabling the feature for the first time, keep in mind that the new update will disconnect all previously linked devices and prompt you to reconnect them. Furthermore, if you do not use the WhatsApp app on your smartphone for more than 14 days, WhatsApp will unlink your linked devices.
