hello everyone a few days ago i did tried to implement a one time purchase (make a paid android app ) there is no error showing except the message that i will show you next thing i did consider: Make sure the product ID in your code matches the ID of the product you created in the Google Play Console. Make sure that the product is published and active in the Google Play Console. Make sure that the account you are using to test the app is not the same account you used to create the product in the Google Play Console. i don't know what I'm missing i keep thinking that the new library is the problem (because its come with new change to how to implement purchase) i did publish the app in Internal testing. i did multiply approach and multiply attempt to fix this with no luck yet with the help of chat gpt . ps : following this topic.
