After trail expired not charge for public app

7 0 0

Hello folks !!
Hope you are doing well !!!  
I would very much appreciate it if you took some time off to address this issue that I am facing

So I have created a public app. and for billing, I have been using "Recurring API".  I'm testing my app, In-app I allow them 1 days trial. But when I testing it, even the trial time already expired. But still, shopify doesn't charge after the trial expired.
