As reported by many users, everything indicates that this innovative functionality has left its beta stage and is available, at least on some platforms.
Currently, WhatsApp Web can work even if the phone is not connected to the Internet or it is not turned on. The same goes for the desktop version of WhatsApp.
Then you have to enter the web or desktop version and scan with a file camera QR code with the device to be displayed on the screen.
WhatsApp allows you to connect up to four additional devices without having to connect the main phone.
Currently, this new multi-device mode is available in the iOS and Android mobile app, as well as the desktop version and WhatsApp Web.
Of course, they explained from the messaging service that the same account cannot be used on two phones, although this function is expected to be activated soon.
Although multi-device support is already available, it is likely that not all users will be able to access it immediately.
At the moment, it is not known when it will be active for all who use the popular messaging app, but it should gradually reach users.
