I hope you having a good day!
It seems my existing question make your team confuse, I will list again to make this simple.
I tested ProSites checkout with PayPal sandbox, and everything was done in papal account, but even after made a payment, the test user is still free user.
Is this due to sandbox account?
I want to know about whether this is a normal behaibor.
