I have a question on in app purchase I have a requirement like user can get the premium account from in app purchase in the app to extend usage of the the existing functionality. The same feature can be brought from the website by logging into his account in web. If user buys the product from web and does login in the iPhone app, are we suppose to unlock this feature in iPhone? Apple doesn't say abut these kind of flows in their docs.
Since the premium account is a subscription based product like purhasing for 1 month or 1 year and not auto renewal. User has to buy the premium service once it expires.
So is my server has to maintain status like is logged in user is premium user or not?
Thanks
