Overview

• Beta version 2.2569.0.0 replaces the native UWP framework with a Progressive Web App rendered through Microsoft Edge WebView2
• Meta expects the unified web approach to simplify development and maintenance by using a single codebase across platforms
• Early tests by WindowsLatest show the new PWA consumes about 30% more RAM than the native app and runs multiple additional processes
• Core Windows integrations such as offline message access and system notifications face reduced performance and reliability under the web wrapper
• Meta has not announced when the WebView2-powered client will replace the stable native app for all Windows users
