Testing In App Purchase Server to Server Notifications Sandbox

I have been testing server to server notifications but I am not sure of getting the following notifications on sandbox. I have enabled the grace period on my app store connect account but how to fall the billing to be failed to renew and test grace period concept. Can any one help me on the actions to be performed for getting following notifications on Sandbox? 1, DID_CHANGE_RENEWAL_STATUS -> AUTO_RENEW_ENABLED, AUTO_RENEW_DISABLED

2, EXPIRED -> BILLING_RETRY

3, GRACE_PERIOD_EXPIRED

4, DID_FAIL_TO_RENEW -> GRACE_PERIOD

5, DID_RECOVER

6, REVOKE

Same issue here! I'm wondering did you find any solution for this? Thanks!

Same here. After disabling "Allow purchses & Renewals" to simulate a billing issue, we only get the DID_FAIL_TO_RENEW with null subtype. Were you able to find a solution to this ?
