We are seeing trial conversions for our auto-renewable monthly subscription wingman_monthly (App ID 6758346525) land in a persistent "Pending" state in users' iOS Purchase History after the 3-day free trial ends, with no debit reaching the user's payment method.
App Store Server Notifications V2 indicate the renewals succeeded — each affected transaction is delivered as DID_RENEW (subType BILLING_RECOVERY not present) with is_trial_conversion: true, period_type: NORMAL, a new expires_date set 31 days in the future, AUD 19.99 attributed, no expirationIntent, no is_in_billing_retry_period, and no cancellation_reason. So Apple's billing layer reports the renewals as successful, but settlement does not appear to complete.
The same trial-to-paid flow on our yearly product wingman_yearly in the same subscription group converts and debits cleanly. The pattern is specific to wingman_monthly.
