How many days before renewal (expiration date)
can a BILLING_ISSUE event come from Apple?
In Apple's documentation they say that they try to see if there is a problem with a payment with the customer 10 days before and 24 hours before
try to renew the customer's subscription several times.
I was in doubt if I can receive a BILLING_ISSUE 10 days before that period or if it would only be within 24 hours before.
