The new function is designed to alleviate users from being interrupted by unintended audio or unavoidable background noise during group calls. It differs from the options provided in other popular tools such as Zoom and Teams, both which only allow you to mute all participants. The feature was recently promoted by the head of WhatsApp, Will Cathcart, and will provide a more granular level of control for call participants… In addition to the mute function, WhatsApp is also rolling out the ability to join in-progress calls. As described by Meta, the new join functionality is a way to maintain the natural flow and spontaneity of calls. Rather than having to answer the call when it starts, participants will now be able to join an in progress call or, if needed, drop and later reconnect to the same call. The new mute and join call functionality are just two more features in a growing list of recent WhatsApp additions. Since late last year, WhatsApp developers have delivered end-to-end encryption (E2EE), the ability to move content from Android to iPhone devices, and the ability to hide your last seen status from other users.
