'The app is a beta version, but we have tested it and it’s incredibly stable because it is native and it uses less resources than WhatsApp Desktop, even if some features are still missing: it’s a very good replacement for the current WhatsApp Desktop app,' the platform said. According to WAbetainfo, a website that tracks WhatsApp, revealed that the new Windows app requires multi-device features, so it doesn’t need your phone to be connected to the Internet to work.
