Use Json logic?
I don’t know what is it.
Where can I find a tutorial teaching the usage of json for updating an app without losing progress files?
I only found this: http://docs.coronalabs.com/api/library/json/
It does not teach that task.
I’m with this problem too. I received negative reviews in google play after I updated my game, because people have lost their progress.
Please help me.

It goes over the process of saving and loading data with Corona SDK. You are going to use JSON to save the data but you don’t need to know anything about JSON to make it work.

I used Rob’s information and now I have a fully modular data system I can plug into any project. IMO having some kind of JSON/SQLite implementation should be step 2 in learning development. Users always want to know how far they have gotten and their score from last game!
Actually GGData works properly. Game progress saves and the game updates.
I think, I have messed up with the versions of the app on my phone, as I got the updated version directly on the phone so in Google Play it was marked as already updated. Everything works fine now.
