The question is for an iOS app -
My setup is that I am using my backend to give access to “Pro” features through the API and I am using Revenue cat to process the payment.
Sign up comes after the purchase is made and it is optional to the user.
I want to understand how I should give access from the backend to users who are making a purchase but do not sign up? This approach should also work when the user comes back and restores purchase after uninstalling the app.
