Hello guys!
We are having many problems with price caching from products, getting the product from Google Play using In App Purchasing.
We can get the price in the first time when app open, but when need update the price in Google Play Console, the price don’t update in game. But when click to buy the game, the Google Play modal show the correct price.
We try use IAP version 2 with Unity 2019.3.0.f6 and now using IAP 4.1.2 and using Unity 2021.2.7.f1. Both versions have the same problem.
We tried force update the price getting again the product using the method “FetchAdditionalProducts” but this doesn’t work too.
Even opening and closing the game many times this make no difference.
We think this problem is with IAP caching, specifically in "product.metadata".
