Hello. We experience issues with in-app purchases in certain countries. Everything works properly in the US, however, we got complaints from our users from several other countries (e.g. Germany, UK, Japan, Canada). When the users try to purchase premium version of the app via IAP that they are charged several times, but in-app purchase is not activated.
We have the common implementation for all countries and nothing specific for the US. Are you aware of such an issue? Could we miss something in the implementation or configuration?
