Teams Manager is constantly evolving to meet industry demands and improve your day-to-day communications. This process includes the addition of new features, changes to old ones, and alterations in layout.
As of now, we don't have an option to switch to the "Old Layout" since we're expecting users to utilize the current version of the app.
If you have feedback related to where elements are placed, feature suggestions, or issues affecting your general operations, feel free to contact your account manager so they can pass it on to us for consideration.
