App Store Server Notification Issue

Hello, I am writing this because the behavior of the App Store Server Notification that our server receives is problematic in the Sandbox environment. I have two questions in total.

  1. When purchasing a Free Trial subscription, after receiving the SUBSCRIBED / INITAL_BUY Notification, DID_RENEW should be sent when it expires, but DID_FAIL_TO_RENEW/GRACE_PERIOD is sent.
  2. The EXPIRE Notification is sent after the subscription expires or DID_CHANGE_RENEWAL_STATUS/AUTO_RENEW_DISABLED is sent, but it does not arrive.

The first problem is that I recently heard that automatic payments after a free trial require the user's consent via email. Is this the reason? If so, I am curious about how I can test it in the Sandbox environment. Is the second problem a bug?
