I am having this problem with macOS when I ‘package’ my game via the editor.
The CFBundleShortVersionString in the generated application’s plist is set to the unreal version number (5.3.2), not the “Project Version” in version settings.
Per a link on this thread as a recommendation for iOS, I tried to add the following to the /Script/MacTargetPlatform.MacTargetSettings, but it does not work for macOS:
AdditionalPlistData=<key>CFBundleShortVersionString</key><string>0.9.25d</string>
The only way I’ve been able to get the proper version is to compile the game directly with Xcode, which will use the Xcode “General…Identity…Version” number. However, there are other issues when compiling directly with Xcode.
