Microsoft Teams: Unblock users to send message while file is uploading in the background

From Microsoft's description: “This allows users to continue sending messages while the file uploads in the background, enabling a more seamless and uninterrupted collaboration experience.”

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.
