WhatsApp has just submitted a new update through the TestFlight beta Program (currently closed), bringing the version up to 2.21.30.16. What’s new in this update? Discover everything below!If you follow WABetaInfo since a long time, you know that WhatsApp is working on a feature that allows to use the same WhatsApp account on different devices at the same time: this feature is called multi device. WhatsApp is developing two different kinds of multi device:

Multi device with WhatsApp Web: you can use WhatsApp Web without your main phone to be connected to the Internet. Multi device with other devices: you can connect up to 4 different devices to your main WhatsApp account. Note that this limit might change in future and this type doesn’t require an active Internet connection on the main phone as well. Today, thanks to the 2.21.30.16 beta update, we want to publish our demo video that shows how to log out from a WhatsApp account from a linked device.
