We are trying to implement Android In-App Billing in our game, made with Unity. The plugin we are using seems to work fine, and I have successfully been able to access Google's In-App billing service in an older project. However, when I try to do a test purchase in our new project (using a test account), I am getting this error: "unexpected response code 403 for https://android.clients.google.com/fdfe/preparePurchase".
I have searched for similar cases on StackOverflow and Google, however none of the solutions I have seen fixes our problem. I believe all our settings should be correct: - The devices we are testing on have had their main accounts added to the list of testers (on Developer Console) and are not Google developer accounts. - The APK has been uploaded and released as alpha, - The in-app product we are testing with has been activated. - Permission for com.android.vending.BILLING has been added to the manifest.
And here is our log:
