I need to check the typical versioning format for mobile apps. Usually, they follow major.minor.patch (e.g., 15.0.1). Version 44.2 might refer to a specific release, but it's possible that the user is referring to an older or a beta version. However, in the app stores (Google Play and App Store), they usually don't allow downloading old versions. So the user might be looking for a method to download an earlier version outside the app stores, which brings up potential security and legal issues.
