I know this is a repeat question but i have minor different errors.
I have implemented in-app billing into my app in flutter. That perfectly work on android version - 7.0, 9.0 but when i try to test on latest OS (11.0) that not working and shows one error "This version of the application is not configured for billing though Google Play " when i try to buy. Still, perfectly get data of in-app billing in Android OS 11.0.
I have already followed answers of questions on StackOverflow like below. But still not solved.
