Hey @yavuzakyazici!

You can customize the test renewal rate in a couple places - if you’re testing iOS and using a StoreKit config file, you can update this on Xcode directly, in the “Editor” tab, under “Subscription Renewal Rate”. If you’re testing iOS but not using a config file, you can update the renewal rate in the Sandbox account settings of your test user: https://developer.apple.com/help/app-store-connect/test-in-app-purchases/manage-sandbox-apple-id-settings

For Google Play, I believe the renewal rates are set and cannot be customized:  https://developer.android.com/google/play/billing/test#renewals

Wow great, detailed, to the point info Thanks...
