Android IAP problem

Hi!
On iOS IAP works fine, on released version i can make a success purchase, but on Android i have a problem. Nothing happen after m_StoreController.InitiatePurchase(product);
In Previous game build i use Codeless IAP and on Android works fine, but in Unity 2019 have some problem with Codless IAP Button on iOS, now i use code to add product and initiate purchase and all works fine but not on Android.
The system of communicating vessels?
- i see metadata from store (price)
- debug log give me a product is not null and product available
- after m_StoreController.InitiatePurchase(product) nothing happen
- same code works fine on iOS

Here's a big thread about the issue: https://forum.unity.com/threads/exc...unityengine-vr-vrsettings-get_enabled.518868/

 

Thank you, but now the API change window does not appear, there is also a forum for this. What a curse to release the game on Unity 2019
