WhatsApp: Multi-device support 2.0 is coming
The feature will likely be rolled out as a beta in the coming weeks before it is officially made available to all users. In addition to the latest discovery, WhatsApp appears to be currently working on implementing multi-device support 2.0. This should also include a native iPad app. This means that users will be able to access their WhatsApp account regardless of the phone in the future. (Photo by Unsplash / Jeremy Zero)
