WhatsApp has reportedly been working on multiple device support lately and is also currently running a beta test of it for WhatsApp web. This most likely means that the feature could be out any time soon for both iOS and Android users.
The multiple device support would let users use their account through four desktop devices if they participate in the beta program, which will be available for both regular users of the app, as well as business account holders.
Once this update is officially out, it is likely to be an important one for those users who greatly depend on WhatsApp web. It will also resolve the issue of having to use WhatsApp Web while being constantly connected to the internet on one’s smartphone.
