Description
Large file sharing in Teams today introduces blocking behavior, forcing users to wait for uploads to complete and disrupting real-time collaboration. To improve productivity and reduce perceived latency, we are introducing asynchronous file uploads. This allows users to continue sending messages while the file uploads in the background, enabling a more seamless and uninterrupted collaboration experience.
