I am currently charging a fixed fee on a monthly subscription plan and a usage charge every week. I would like to give the users the option to pay the fixed fee at a discount once per year but also charge them every month based on usage. I've tried implementing this by using the annual interval in appSubscriptionCreate, but the issue that I run into is that when the annual subscription is created and activated, the monthly one is deactivated. Since usage charges are not allowed in annual subscriptions, I tried to create another monthly one to be able to charge usage but then the annual one gets deactivated.
Is there a way to have both annual and monthly recurring_charges active at the same time? ie. is there a way to use usage charges and have an annual subscription plan?
Thank you for your time.
