We are trying to change the current price of a customer's subscription after the customer clicks on an item to purchase that would increase their billing cycle. We have looked into the Subscription + Item Payment, however, that seems to not work anymore. Would there be a way to change the amount that the customer is being billed for without having to add multiple dropdowns that would be controlled programmatically so the customer would not view the dropdowns. They would just click on an item that they want to include on their plan and click on update. This goes the same way for if the customer wants to remove an item from their plan. If we were to hard code the dropdowns to work programmatically, we would have over 10,000 dropdowns for all of the variations that the customer could choose from. It would be more simplified to just change the total cost before adding in taxes and fees. Thanks.
