I’m a unity Mobile game developer. Because of the Google Play Billing Library Migration I updated my In-app purchase package manager to 4.12.2 and the latest external dependency manager also. In the IAPAndroidDependencies file I can see the billing client 6.2.1. I didn’t changed any of my purchasing script. After I updated all those I submitted and still I get the error message of the Google Play Billing error. What should I do to solve the issue?

I updated the unity In-app Purchasing package.
I updated the ExternalDependencyManager also
