WhatsApp is testing a new feature that will allow users to communicate with people using third-party messaging apps. This capability is currently being rolled out in beta, but it's restricted to certain regions, primarily Europe, due to regulations like the Digital Markets Act. Users will eventually be able to chat seamlessly with contacts outside WhatsApp, similar to SMS conversations, supporting messages, images, videos, and voice messages. WhatsApp will provide a way to differentiate these chats from regular ones, making it clear when users are engaging with contacts from outside the app. At this stage, only one third-party app, BirdyChat, is supported in the beta version. This limited availability means that while the feature has potential, its full rollout will depend on how other apps adapt to the requirements set forth in Europe. The timeline for broader interoperability remains uncertain, as it will hinge on individual app developers' readiness. For those interested in trying it out, there's an option to join the beta program via the Google Play Store, but it's exclusive to users in Europe.
