How to initialize UDP using IAP?

Monetization & Growth In-App Purchases

Hello all,

I am using IAP with code, and now I am trying to test sandbox of UDP.
As documentation says I just switched the target store to UDP,
Using the editor it works,
When I load it on android it does not get initialized, it does not fail, it does not succeed, nothing happens and the sandbox login does not popup.
Do I have to call something else other than UnityPurchasing.Initialize(this, builder);?

thanks in advance.
