How to get Android project setting values

I configured the android project setting values. Whenever I update the game with fixes, the store value is incremented. The store value is used to show update and represents the newer version. Now, I want to show it to the user in the game if they are using the older version. But, I am unable to access the android store version of the game

I tried to do this by referring this link - How get Project Settings values? - Programming & Scripting - Unreal Engine Forums

    GConfig->GetString(
	        TEXT("/Script/EngineSettings.GeneralProjectSettings"),
	        TEXT("StoreVersion"),
	        AppVersion,
	        GGameIni
        );

Is it possible to access the value ??

Thanks

I would like to know this as well. I have no success reading from the EngineSettings on an Android device. Also tried to load configs first.
