scenario:
postpaid account
recurring DID product
monthly billing schedule with billing date on the 1st of each month

issue:
for the initial month, everything is working fine. DID and minute charges are populated on the invoice correctly.

but for the subsequent months, only the minutes from the first month is showing on the invoice, even though there are additional usage.  On the screenshots below, the October and November invoices are having the same minutes charges (usd18.69), and both are dated “01-09-2022”. This is actually the minute usage of August, while there are additional calls on September and October.
