New Microsoft Teams: “A simpler user experience” The speed optimization changes mean that Teams users will be able to load the app, join meetings, and switch chats and channels up to two-times faster on average compared to classic Teams. “Our efforts to update the core technology have been a good move towards providing a more efficient and dependable Teams app,” Pattnaik said. This, the firm said, is because resources are shared with Edge. The new app uses Edge WebView2 as the host for the platform, which has reduced memory usage and disk space.

The latest version of the productivity platform has been built on the React framework, which Microsoft said has enabled it to improve speed and performance of the app for Windows users.
