The sandbox environment also supports this subscription renewal rate. For more information about renewal rates in the sandbox environment, see [Test Apple In-App Purchases](https://help.apple.com/app-store-connect/#/dev7e89e149d).

The time rate also affects the billing grace period and the billing retry period in the testing environment, as the table below shows:

|-------------------------------------------------------------|--------------------|
|Grace period for subscriptions with a weekly renewal period  |4 minutes 17 seconds|
|Grace period for subscriptions with all other renewal periods|7 minutes 30 seconds|
|Billing retry period                                         |30 minutes          |
