Microsoft has overhauled the Teams Files App as part of its work to refresh the Teams client UI. We’re still waiting to know about the new channels experience which is supposed to appear at around the same time. This work will refresh and enhance the Teams V1 client while also appearing in the Teams V2.1 client that’s expected to be available in preview soon.
