In my case, I have an app which it contains 3 user membership type. I know I'm gonna implement the app purchase but that's not what i mean. Let's take a look at the example.
We got 3 memberhsip. Bronze, Gold and Premium. Let's say someone bought Gold membership. And I want to give him access to all Bronze and Gold's features and don't allow for *Premium's features*.
This logic is new for me. How can I handle with this ?
