The Server-Side Problem

Unlike offline games, Facebook is a social media platform heavily reliant on server-side communication. Even if you successfully install an APK from three years ago, the app communicates with Facebook’s servers.

Meta frequently updates its API (Application Programming Interface). If the API changes, the old app may fail to load the news feed, display images, or allow comments. A version that is too old will simply present a "Login Failed" or "Update Required" message, forcing the user to upgrade.
