Subscriptions updated from the Customer Portal can now also modify their billing cycle anchor
What’s new
When customers update their subscription from the customer portal, you can now configure the billing_cycle_anchor that applies to the updated subscription by specifying a Customer Portal Configuration. The billing cycle anchor is the reference point that aligns future billing period dates, defined as a UNIX timestamp in seconds from the current epoch, or now (the current UTC timestamp).
Impact
You can now control the billing cycle anchor that applies when customers update their subscription from the customer portal. This change gives you more flexibility when you reset the billing date during subscription updates. Previously, updates made from the customer portal would always retain the existing billing cycle anchor.
