Android problem - no popup window

Hello! I have a problem on unity 2018. In Unity 5, everything works great! But in Unity 2018 in Android, the purchase works without errors, but there is no pop-up window. In the editor, the purchase works without problems!

Actual purchases don’t occur in the Editor, they are fake purchases only. And I’m not sure what you mean purchases work without error on Android, a popup for the user to confirm their credit card purchase is required. Please elaborate.

The problem was solved you can close the topic. The problem was in an incorrectly configured time zone, when importing Unity Iap, I could see errors related to time synchronization that I did not notice.
