IAP purchase doesn't work in andorid

IAP work on the editor and return the success result, but in build (Android), in purchase it debugs: Purchasing product asynchronously, and then nothing happens (but it should open google play's payment activity). If i try to buy the product again, it debugs: Existing purchase pending. I followed this link https://unity3d.com/ru/learn/tutori...94.1620493377.1548055497-498715176.1536677987

I added everything correct: all IAP catalog in unity and in Play Console, everything correct (all ID's and names, but prices can be different). Then uploaded to alpha testing, and download by link.

Logcat shows this when i purchase first time:

 

Are you using Codeless IAP by chance? If so, please ensure you have the Consume Product checkbox set. You can also test with the sample IAP project here https://forum.unity.com/threads/sample-iap-project.529555/
