Is there some detailed help/tutorials available, or could somebody help out, with how you go about handling consumable purchase history if somebody deletes an app, then later re-downloads it - or even just moves to a new phone.
Like, if your game has a... "50 coins" "100 coins" "500 coins" set of purchases. A player buys 3 lots of 100 coins. And they spend 150 of them to unlock something in the game, maybe to unlock a new spriteset or whatever they can spend those coins on.
And then they get a new phone...
On both Google, and Apple, how do you go about getting that data back? How do you get their account back to 150 coins, and grant them whatever client-side things they'd unlocked with those consumable purchases?
Is there a simple/nice example set of code out there which handles this all smoothly in an easy to understand manner, please, or can somebody help with how to handle this?
