I'm an app developer, and I recently launched a monthly subscription product in my app on the App Store. However, I'm having trouble understanding the App Store's renewal date calculation policy. According to the official documentation, if a subscription is purchased on December 1st, the next renewal date should be January 1st. But the expiresDate is set to December 31st instead. At first, I thought this might be a timezone issue, but even after it became December 1st in UTC, the renewal date was still set to December 31st. Is the timezone used to calculate renewal dates not UTC+0? Or is there documentation on the renewal cycle policy that I might have missed? Any clarification would be greatly appreciated. Thanks in advance!
