I Can’t Make In-App Purchases in Coin Master on Android

For about one year, I have been unable to make in-app purchases in the Coin Master game on my Android device. Every time I try to make a purchase, I receive an error message and get redirected to the support page. However, since the redirected page is entirely in English, I am unable to explain my issue properly or find a solution.

I have tried making purchases using both mobile carrier billing and a credit card, but I encounter the same problem with both payment methods. I also tested different internet connections (Wi-Fi and mobile data), but the result did not change. I uninstalled and reinstalled the app and made sure it was fully updated, yet the issue still persists. In addition, I am experiencing similar in-app purchase problems in other apps, not only in Coin Master.

I request that in-app purchases be fixed so they work properly, and that Turkish-language support be provided so my issue can be resolved.
