I have an app currently in alpha, and I am thinking of moving to beta soon. Once I do this step, I want to re-initialize local files as the game changed quite a bit (local scores, etc.), and display a "Thank you for testing the alpha-version"-message and whatnot.
To do this, I would like to check whether the first time the user installed my app from the app-store was during the alpha, i.e. whether the version corresponds to one of the version of alpha. I found that it is possible to get the time the app was first installed, but haven't found a way to retrieve the version.
Short story long: is there a way to get the version of the app the user installed it for the first time?
P.S. If possible, I would like to achieve this in Unity
