How to verify whether the internal purchase of channel APK created by unity distribution portal is c

The migetapp and Huawei channel APK I created after connecting to UDP SDK and passing sandbox test cannot use payment function normally. Specific symptoms: click payment, the pop-up payment page will be automatically closed, and there is no subsequent payment process. I don’t know if it’s right or wrong. I hope to get help.

Could you provide the device log for the investigation? Thanks.
