If a user is subscribed to PREMIUM YEARLY with access to Bachata, Lindy Hop, and Kizomba, and less than one year later, they want to upgrade to PRO YEARLY, the following applies:
Billing Change: The user will be charged the difference between the remaining value of their PREMIUM subscription and the cost of the PRO subscription. The payment amount gets updated, but the billing date remains the same.
Billing Period: The billing period remains aligned with the original subscription (PREMIUM YEARLY) until its natural expiration. After that, the new billing period will commence with the upgraded plan (PRO YEARLY).
Upgrade Application: The new upgrade is typically applied immediately if everything goes smoothly. Users should see the enhanced access reflected as soon as the upgrade transaction is completed.
Installment Payments: Typically, installment payments are not accepted for such upgrades. The user is charged the full difference between the remaining value of their current plan and the cost of the new plan.
