MLex Summary: European users will soon be able to contact a wider range of chat services via WhatsApp after owner Meta Platforms announced interoperability functionality for its messenger app. The changes are being rolled out to comply with the Digital Markets Act, and BirdyChat and Haiket are the first third-party services to be interoperable with WhatsApp. While users will be able to share messages, pictures, voice messages and videos, the option to create groups will take a little longer to be become available.
